Islamic eschatology

From Wikipedia, the free encyclopedia
 

Islamic eschatology is the aspect of Islamic theology incorporating the beliefs and the Islamic eschatological narrative regarding signs of tribulation, the end of the world, and afterlife with the resurrection of the dead, the final judgment, and the eternal division of the righteous and the wicked.

Similarly to the other Abrahamic religions, Islam teaches that there will be a resurrection of the dead that will be followed by a final tribulation and eternal division of the righteous and wicked. The Great Tribulation is described in the ḥadīth literature and commentaries of various medieval Muslim scholars, including al-Ghazali, Ibn Kathir, and Muhammad al-Bukhari, among others. The Day of Judgement is referred to with several names throughout the Quranic text, such as the Day of Reckoning, the Last Day, and the Hour (al-Sā'ah). Islamic apocalyptic literature describing Armageddon is often known as fitna, Al-Malhama Al-Kubra (The Great Epic), or Ghaybah (Occultation) in the Shīʿa branch of Islam. The righteous are rewarded with the pleasures of Jannah (Paradise), while the unrighteous are punished in Jahannam (Hell).

The ḥadīth literature describes several events happening before the Day of Judgment, which are described as "minor signs" and "major signs". During this period, terrible corruption and chaos would rule the Earth, caused by Al-Masih ad-Dajjal (an eschatological figure similar to the Antichrist in Christianity), then the Mahdi (a righteous man descended from the Islamic prophet Muhammad), assisted by the prophet ʿĪsā (Jesus) who will return to Earth, will defeat the Dajjal and establish a period of peace, liberating the world from cruelty and injustice. These events will be followed by a time of serenity when people will live according to religious values.

A 2012 poll conducted by the Pew Research Center found that 50% or more respondents in several Muslim-majority countries (Lebanon, Turkey, Malaysia, Afghanistan, Pakistan, Iraq, Tunisia, and Morocco) expected the Mahdi (the final redeemer according to Islam) to return during their lifetime.

Sources for Islamic eschatology

Islamic scripture has a plethora of content on the Last Judgment and the tribulation associated with it. The two sources which are primarily referred to when exploring the topic of Islamic eschatology are the Quran itself and the hadith, or accounts of the actions and sayings of Muhammad during his lifetime. One of the functions of the Quran as it relates to eschatology and the Day of Judgement is to serve as a reminder of Allah's intentions for humanity and as a warning for those who do not abide by Him. Hadith are often referred to in tandem with the Quran in order to create a more detailed and comprehensive understanding of Islamic scripture. The compilation of hadith took place approximately two hundred years after the death of Muhammad. The Last Judgment and the tribulation have also been discussed in the commentaries of ulama such as al-Ghazali, Ibn Kathir, and Muhammad al-Bukhari. Scholarly discourse on eschatology and its sub themes often includes an exploration of hadith as they pertain to matters in the Quran, and serve as a source for clarification. Hadith are generally viewed as being second in authority to the Quran, as the Quran is generally understood to be the verbatim word of God.

Signs of the End Times

In Islam, there are a number of minor signs and major signs. The Mahdi is said to be a link between the minor and major signs. In the Hadith, it is mentioned that minor signs will occur first, then the Mahdi will come and then the major signs. There is debate over whether they could occur concurrently or must be at different points in time.

However, these signs aforementioned are not all based on reliable hadiths and if one of them is based on a reliable hadith, it could not be treated as a commandment or a prohibition.

The Mahdi

Mahdi (Arabic: ٱلْمَهْدِيّ, ISO 233: al-mahdīy), meaning "Rightly Guided One" is a messianic figure in Islamic tradition. He makes his first appearance in the hadiths and is said to be the sign between Minor signs and Major signs of Day of Resurrection. Some Shia Muslims regard him as the first sign of the third period. Hadith reports state that he will be a descendant of Muhammad through Muhammad's daughter Fatimah and cousin Ali's son Hassan. According to Shias, Mahdi will be looked upon to kill Dajjal to end the disintegration of the Muslim community, and to prepare for the reign of Isa (Jesus), who will rule for a time thereafter. According to Sunnis, Mahdi will be against Dajjal and will have some Muslim communities in Shaam and that Jesus will return to kill Dajjal. The Mahdi will fulfill his prophetic mission, a vision of justice and peace, before submitting to Jesus' rule. The physical features of Mahdi are described in the hadith; he will be of Arab complexion, of average height, with a big forehead, large eyes, and a sharp nose. He will have a mole on his cheek, and be recognized by the Muslim community while he sits in his own home. As written by Abu Dawud, "Our Mahdi will have a broad forehead and a pointed (prominent) nose. He will fill the earth with justice as it is filled with injustice and tyranny. He will rule for seven years." In some accounts, after the seven years of peace, God will send a cold wind causing everyone with the smallest measure of human-kindness or faith, to die and carry them straight to heaven. Therefore, only the wicked will remain and be victims of terrible animals and Shayateen, until the day of resurrection.

Though the predictions of the duration of his rule differ, hadith are consistent in describing that God will perfect him in a single night, imbuing him with inspiration and wisdom, and his name will be announced from the sky. The Mahdi will bring back worship of true Islamic values, and bring the Ark of the Covenant to light. He will conquer Constantinople and Mount Daylam and will regard Jerusalem and the Dome as his home. His banner will be that of Muhammad: black and unstitched, with a halo. Furled since the death of Muhammad, the banner will unfurl when the Mahdi appears. He will be helped by angels and others that will prepare the way for him. He will understand the secrets of abjad.

Sunni and Shia perspectives

Sunni and Shia Islam have different beliefs regarding the identity of Mahdi. Historically, Sunni Islam considers religious authority as being derived from the caliph, who was appointed by the companions of Muhammad at his death and the companions of Muhammad. The Sunnis view Mahdi as a leader that is expected to arrive to rule the world and reestablish righteousness. Sunni Muslims also believe that Mahdi's name will be Muhammad and his father's name will be Abdullah, thus making his full name Muhammad ibn Abdullah. However, Twelver branch of Shias believe that Mahdi will be the twelfth Imam. Shia Muslims believe his name is Muhammad bin Hasan and that he is the son of Hasan-al-Askari. Shias believe that Mahdi hid in 873 when he was four. He maintained contact with his followers until 940, when he entered the Occultation. Twelver branch believes that al-Mahdi is the current Imam, and will emerge at the end of the current age. Some scholars say that, although unnoticed by others present, the Mahdi of Twelver Islam continues to make an annual pilgrimage while he resides outside of Mecca. In contradistinction, Sunni Islam foresees him as a separate and new person. Sunni tradition has attributed such intellectual and spiritual attributes to numerous Muslims at the end of each Muslim century from the origin of Islam to the present day. Sunni Muslims also believe that the Isa (Jesus) will pray behind Mahdi. The present Ayatollahs of Iran see themselves as joint caretakers of the office of the Imam until he returns.

The Mahdi is not described in the Quran, only in the hadith, with scholars suggesting he arose when Arabian tribes were settling in Syria under Muawiya. "They anticipated 'the Mahdi who will lead the rising people of the Yemen back to their country' in order to restore the glory of their lost Himyarite kingdom. It was believed that he would eventually conquer Constantinople."

According to Nasir Khusraw, a celebrated Fatimid thinker, the line of Imams from among Imam 'Ali's descendants though Imam Husayn will eventually culminate in the arrival of the Lord of the Resurrection (Qāʾim al-Qiyāma). This individual is believed to be the perfect being and the purpose of creation, and through him the world will come out of darkness and ignorance and "into the light of her Lord" (Quran 39:69). His era, unlike that of the enunciators of divine revelation (nāṭiqs) who came before him, is not one where God prescribes the people to work. Rather, his is an era of reward for those "who laboured in fulfilment of (the Prophets') command and with knowledge". Preceding the Lord of the Resurrection (Qāʾim al-Qiyāma) is his proof (ḥujjat). The Qur’anic verse stating that "the night of power (laylat al-qadr) is better than a thousand months" (Quran 97:3) is said to refer to the proof of the Lord of the Resurrection, whose knowledge is superior to that of a thousand Imams, though their rank, collectively, is one. Hakim Nasir also recognizes the successors of the Lord of the Resurrection to be his deputies (khulafāʾ).

Major signs

Following the second period, the third will be marked by the ten major signs known as alamatu's-sa'ah al-kubra (the major signs of the end). They are as follows without any exact order:

  1. A huge black cloud of smoke (dukhan) will cover the earth.
  2. Three sinkings of the earth, one in the east.
  3. One sinking of the earth in the west.
  4. One sinking of the earth in Arabia.
  5. The coming of Dajjal, presuming himself as an apostle of God. The false messiah—anti-Christ, Masih ad-Dajjal—shall appear with great powers as a one-eyed man with his right eye blind and deformed like a grape. Although believers will not be deceived, he will claim to be God, to hold the keys to heaven and hell, and will lead many astray. In reality, his heaven is hell, and his hell is heaven. The Dajjal will be followed by seventy thousand Jews of Isfahan wearing Persian shawls.
  6. The return of Isa (Jesus), from the fourth sky, to kill Dajjal.
  7. Ya'jooj and Ma'jooj (Gog and Magog), a Japhetic tribe of vicious beings who had been imprisoned by Dhul-Qarnayn, will break out. They will ravage the earth, drink all the water of Lake Tiberias, and kill all believers in their way. Isa, Imam Al-Mahdi, and the believers with them will go to the top of a mountain and pray for the destruction of Gog and Magog. God eventually will send disease and worms to wipe them out.
  8. The sun will rise from the west.
  9. The Dabbat al-Ard, or Beast of the Earth, will come out of the ground to talk to people.
  10. The first blow of the trumpet will sound and everything will fall dead
  11. The second blow of the trumpet will be sounded, the dead will return to life, and a fire will come out of Yemen that shall gather all to Mahshar Al Qiy'amah (The Gathering for Judgment).

Descent of Jesus

Islamic literature predicts that the Mahdi will be followed and assisted in his fight against evil "by a bygone prophet who will come back to earth". This prophet will not be Muhammad (as non-Muslims might expect) but ʿĪsā (Jesus), 'praised in the Quran as the Messiah and the “Word of God.”' "The usual interpretation" of the prophecy of Jesus's return to earth is that He "will put an end to his own worship, symbolized by the cross, and re-establish the dietary laws that Christianity abandoned but Jews and Muslims still observe." While the Quran is not explicit about Jesus' return, many Muslims believe that at least two Quranic verses refer to his second coming during the end times. The probably most significant verse is Surah 4:157: "And [for] their saying, 'Indeed, we have killed the Messiah, Jesus, the son of Mary, the messenger of Allah.' And they did not kill him, nor did they crucify him; but [another] was made to resemble him to them. And indeed, those who differ over it are in doubt about it. They have no knowledge of it except the following of assumption. And they did not kill him, for certain." The other states: "And indeed, Jesus will be [a sign for] knowledge of the Hour, so be not in doubt of it, and follow Me. This is a straight path". (43:61)." The Arabic language is not clear, as to who the people of the book have to believe in. Tabari author of one of the most important Sunni Tafsirs argues, the verse refers to Jesus, who will unite all believers under the banner of Islam. Hadiths further elaborate the events following Jesus arrival. According to Sahih al-Bukhari, Jesus will descend among Muslims, break the cross, kill the pig and abolish the Jizya. Although traced back to Abu Hurairah, one of the sahaba, such hadiths might actually have been introduced later during civil wars in the early Abbasid Caliphate, when a savior was expected. While for Shias, the Mahdi will be the savior, some Sunnis tended to expect Jesus' return. During the early Abbasid Caliphate, wearing crucifixes in processions and holding pigs in public, was forbidden. Otherwise, the breaking of the cross, might reflect general disapproval of this symbol by Muslims, and slaying pigs a reference to Jesus exorcism of Legion.

Shia eschatology

Various eschatological interpretations exist within Shia Islam. The concept of seven celestial Hells, as well as the idea that one's souls temporarily wait in either Paradise or Hellfire until the End Times, are accounted for throughout Isma'ili Shi'i literature. Shia tradition broadly tends to recognize the coming of the Mahdi as signifying punishment to come for non-believers. Twelver Shia scholar 'Allama al-Hilli expressed that it is not possible for any Muslim to be ignorant of "the imamate and of the Return" and thus "whoever is ignorant of any of them is outside the circle of believers and worthy of eternal punishment." This statement is not indicative of all Shia eschatological thought, but does note the existence of a form of eternal punishment, or realm that is opposite Paradise.

Raj`a

Raj`a (Arabic: الرجعة, romanizedāl rj'ah, lit.'Return') in Islamic terminology, refers to the Second Coming, or the return to life of a given past historical figure after that person's physical death. Shia believe that before the Day of Judgement, Muhammad al-Mahdi will return with a group of chosen companions. This return is more properly known as zuhur or 'appearance,' as the Hidden Imam is believed to have remained alive during his period of occultation, since the year 874. The return of these historical figures will signify the beginning of the Last Judgment. The purpose of this return is to establish justice for those who were oppressed in their lifetime up until their death: the oppressors are punished directly by the oppressed during this future reappearance.

Some Sunni scholars do believe in Raj’a, citing the return of numerous people, such as the Seven Sleepers, synchronous with the appearance of the Mahdi. According to Jalaluddin Al-Sayuti, in contrast to Shia belief, the return of Muhammad is not limited to a specific time in the future. Al-Sayuti did not mention if any other religious figures will return after death before the resurrection. According to Abu 'Abdullah Al-Qurtubi, raj`a is understood to be the lack of physical presence of a prophet, who marks his apparent death by absence in the physical world but will reappear, from time to time, to those who are pure in heart.

Isa

Isa is the Arabic name for Jesus, and his return is considered the third major sign of the last days (the second being the appearance of Jesus's nemesis Masih ad-Dajjal). Although Muhammad is the preeminent prophet in Islam, Jesus is mentioned in the Quran, and so is Idris (Enoch), who is said not to have died but to have been raised up by God. Thus, in accordance with post-Quranic hadith, Jesus conceivably will return to Earth as a just judge before the Day of Judgment.

Hadith reference both the Mahdi and Isa simultaneously and the return of the Mahdi will coincide with the return of Isa, who will descend from the heavens in al-Quds at dawn. The two will meet, and the Mahdi will lead the people in fajr prayer. After the prayer, they will open a gate to the west and encounter Masih ad-Dajjal. After the defeat of ad-Dajjal, Isa will lead a peaceful forty-year reign until his death. He will be buried in a tomb beside Muhammad in Medina. Though the two certainly differ regarding their role and persona in Islamic eschatology, the figures of the Mahdi and Isa are ultimately inseparable, according to Muhammad. Though Isa is said to descend upon the world once again, the Mahdi will already be present.

What will be your reaction when the son of Mary (Jesus) descends and your Imam is from among yourselves? (Sahih Muslim, bab nuzul 'isa, Vol. 2; Sahih Bukhari, kitab bad' al-khalq wa nuzul 'isa, Vol. 4)

Resurrection and final judgement

The resurrection and final judgement are fundamental beliefs in Islam. According to the Quran, without them, the creation of humanity would be in vain. Thus the Day of Judgment, al-Qiyāmah, (also known as the Day of Reckoning or Resurrection, the Last Day, or the Hour) is one of the six articles of faith in Sunni Islam, and one of seven in Shia Islam. It is believed in Islam that the Qur'an states Allah will resurrect everyone from their graves on the day of judgement. It is believed that the time is coming and that there shall be no doubt that Allah will do as promised. Just as Allah created the people, they will be brought back to the same form. Allah will double the deeds of his most faithful servants.

Major events

Kaaba destruction and the beast of the earth

Before doomsday, an Abyssinian, with short legs, will attack Mecca and destroy the Kaaba. Another sign is the appearance of the da'ba-tul-ard, or the Beast of the Earth.

The entire world will be engulfed by dukhan or smoke, for forty days, and there will be three huge earthquakes. The Quran will be taken to heaven and even the huffaz will not recall its verses. Finally, a pleasant breeze will blow that shall cause all believers to die, but infidels and sinners will remain alive. A fire will start, from Hadramawt in Yemen, that will gather all the people of the world in the land of Mahshar, and al-Qiyamah will commence.

Resurrection of the dead

In the Quran, barzakh (Arabic: برزخ) is the intermediate state for the soul, until the day of resurrection.

The eighth sign is a breeze bearing a pleasant scent, which will emanate from Yemen, causing the awliya, sulaha and the pious to die peacefully once they inhale it.

The ninth sign is the rising of the sun from the west after a long night. After midday, the sun will set again. According to hadith:

Abu Hurayrah states that the Messenger of God (saw) said, "The Hour will not be established until the sun rises from the West and when the people see it they will have faith. But that will be (the time) when believing of the soul, that will have not believed before that time, will not benefit it.

— Ibn Maja, as-Sunan, vol. 2 p 1352-53

The final signs will be nafkhatu'l-ula, when a trumpet will be sounded for the first time, and which will result in the death of the remaining sinners. Then there will be a period of forty years, after which the eleventh sign is the sounding of a second trumpet to signal the resurrection as ba'as ba'da'l-mawt. As written in the Quran:

The Trumpet will (just) be sounded, when all that are in the heavens and on earth will swoon, except such as it will please God (to exempt). Then will a second one be sounded, when, behold, they will be standing and looking on!

— Sura 39 (Az-Zumar), ayah 68

All will be naked and running to the Place of Gathering, while the enemies of God will be travelling on their faces with their legs upright. Finally, there will be no more injustice:

Surely God does not do injustice to the weight of an atom, and if it is a good deed He multiplies it and gives from Himself a great reward.

— Sura 4 An-Nisa, ayah 40

Separation of the righteous and the damned

At divine judgment, each person's Book of Deeds will be read, in which "every small and great thing is recorded," but with actions before adolescence omitted. Records shall be given with the right hand if they are good, and the left if they are evil. Even the smallest acts will not be ignored:

Then shall anyone who has done an atom's weight of good, see it!
And anyone who has done an atom's weight of evil, shall see it.

— Quran, Sura 99 Az-Zalzala, ayat 7-8

This will be followed by perfect, divine, and merciful justice. The age of the hereafter, or the rest of eternity, is the final stage after the Day of Judgment, when all will receive their judgment from God.

Indeed, those who believed and those who were Jews or Christians or Sabians [before Prophet Muhammad] – those [among them] who believed in God and the Last Day and did righteousness – will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve.

— Qur'an, Sura 2 Al-Baqara, ayah 62

The dead will stand in a grand assembly, awaiting a scroll detailing their righteous deeds, sinful acts, and ultimate judgment. Muhammad will be the first to be resurrected. According to ancient belief, God will descend to Mount Moriah, where he will judge souls. The complex of the Haram al-Sharif in Jerusalem, built under the Umayyad Caliph 'Abd al-Malik (r. 685-705), might thus be interpreted as a reminder of the approaching Last Judgement.

If one did good deeds, one would go to Jannah, and if unrighteous, would go to Jahannam. Punishments will include adhab, or severe pain, and khizy or shame. There will also be a punishment of the grave (for those who disbelieved) between death and the resurrection.

Resurrection theories

Although Islamic philosophers and scholars were in general agreement on a bodily resurrection after death, interpretations differ in regard to the specifications of bodily resurrection. Some of the theories are the following:

  • The return to the same material body, someone had during lifetime, that will be restored.
  • Conjunction of the soul with a Mithali body, which is congenial to the worlds of Barzakh and the Akhirah.
  • Resurrection with a Hurqaliyati body, accordingly a second invisible body, that survives death.

Eschatological views in the early Muslim period

One of the primary beliefs pertaining to Islamic eschatology during the Early Muslim Period was that all humans could receive God's mercy and were worthy of salvation. These early depictions even show how small, insignificant deeds were enough to warrant mercy. Most early depictions of the end of days depict only those who reject Tawhid, the concept of monotheism, are subject to eternal punishment. However, everybody is held responsible for their own actions. Concepts of rewards and punishments were seen as beyond this world, a view that is also held today.

Limbo Theory of Islam

In terms of classical Islam, the Limbo Theory of Islam, as described by Jane Smith and Yvonne Haddad, implies that some individuals are not immediately sent to the afterlife, but are held in a state of limbo. The fate awaiting all people after their death is either the Gardens, heaven, or the Fire, hell. Traditional interpretations agree that, at minimum, these are two of the possible fates that await the dead. However, some have interpreted 7:46, "And there will be a veil between them. And upon the Heights are men who know all by their marks. They will call out to the inhabitants of the Garden, 'peace be upon you!' They will not have entered it, though they hope". Some have taken the mention of this veil between heaven and hell as an allusion to there being individuals who are not immediately sent to their ultimate destination.

The Current Existence of the Afterlife

There was considerable debate regarding whether heaven and hell exists at the current moment. The Mu'tazila argued that heaven and hell both cannot exist until the trumpet blasts that bring in the end times occurs, as the Quran states that once the trumpet sounds, all except God will be destroyed. However, the Ash'ariya argued that although the trumpet's sounding will precede all being destroyed, creation was a constant process. Furthermore, as Adam and Eve once resided in the Garden of Eden, the garden already exists. Also, hadith reports pertaining to the Night Journey state that Muhammad saw visions of both destinations and creatures inhabiting it. Thus, heaven and hell are usually regarded as coexisting with the current world.

The Concept of Eternity

In Classical Islam, there was a consensus among the theological community regarding the finality of the Gardens; faithful servants of God would find themselves in this heaven for eternity. However, some practitioners in the early Muslim community held a concept that stated that hell may not be eternal in and of itself. These views were based upon interpretations that viewed the upper levels of Hell as only lasting for as long as God deemed necessary. Once Muslims had their sins purged, these levels would be closed. These interpretations are centered on verses 11:106-107 in the Quran, stating, "As for those who are wretched, they shall be in the Fire, wherein there shall be for them groaning and wailing, abiding therein for so long as the heavens and the earth endure, save as thy Lord wills. Surely thy Lord does whatsoever He wills". To this end, the Quran itself gives a conflicting account of Hell, stating that Hell will endure as long as Heaven will, which has been established as eternal, but also the Quran maintains the possibility that God may yet commute a sentence to Hell. In a sense, these levels of Hell were interpreted to have a similar function as Purgatory in Christianity, with the exception to this comparison being that Hell in this context is for the punishment of the sinner's complete body, as opposed to the only the soul being punished in Purgatory. Arguments questioning the permanence of Hell take the view that Hell is not necessarily solely there to punish the evil, but to purify their souls. To clarify, the Garden is the reward while the Fire is for purification.

Gender and Islamic Eschatology

Eschatological beliefs in Islam do not tend to distinguish the afterlife on the basis of gender. Amina Wadud discusses Hell and Paradise in her book "Qur'an and Woman" very briefly. Wadud mentions that the Qur'an does not mention any specific gender when talking about Hell. All genders have an equal chance and consequence to experience hell and one is not over the other. The Qur'an 43:74-76 states that "the guilty are immortal in hell's torment," not he or she. It is directed to the individual and "the basis of faith and deeds," not gender. This is consistent in the Qur'an. Amina Wadud goes on to discuss paradise, and how the Quran describes it with such detail in order to "entice" the readers and make it sound pleasing. Wadud states what the Quran says about good earthly things, and eternal things which includes women. 3:14-15 states "Beautiful of mankind is love of the joys (that come) from women and offspring..."

Predestination

Traditional Islam teaches predestination for both good and evil, and that everything that has happened and will happen has already been determined. Free will and predestination have been discussed by many Muslim theologians; but the believers in free will, also known as al-qadariyya, have been overruled. Muhammad expressed predestination multiple times during his mission. Death is also seen as a homecoming. When people visit tombs, they are having a specific spiritual routine. The correct way to visit someones tomb is to recite parts of the Quran and pray for the deceased.

The fate of non-Muslims

Abu Hamid al-Ghazali categorized non-Muslims into three categories:

  • 1. People who never heard of the message, who live in far away lands, such as the Byzantines ("Romans".) These will be forgiven.
  • 2. People who were exposed to a distorted understanding of Islam and have no recourse to correct that information. These too will be forgiven.
  • 3. People who heard of Islam because they live in neighboring lands and mix with Muslims. These have no hope of salvation.

Although many argue that anybody who thinks logically would eventually find that there is only one true, all-powerful God, however, others argue that if one has never received the message, they are not liable for not following it. This debate has been going on for centuries, however several Muslim theologicians agree that Islam is the only path, no other religion, even the other Abrahamic faiths, are proper paths to salvation. Although the Quran acknowledges the Bible as gospel, rejecting Muhammad and his message is seen as a rejection of salvation by them.

The fate of Jews

The Quran makes a variety of statements on the state of the Jewish community, praising their dedication to monotheism in one line and criticizing their rejection of Muhammad the next. An example of a line criticizing the Jews can be found at 5:60-61: "Say, 'Shall I inform you of something worse than that by way of recompense from God? Whomsoever God has cursed and upon whom is His Wrath, and among whom He has made some to be apes and swine, and who worship false deities, such are in a worse situation, and further astray from the right way.' When they come to you, they say, 'We believe.' But they are certainly entered with disbelief and they have certainly left with it, and God knows best what they were concealing. Thou seest many of them hastening to sin and enmity and consuming what is forbidden. Evil indeed is that which they were doing.". Another example is 5:64: "The Jews say, 'God's Hand is shackled.' Shackled are their hands, and they are cursed for what they say. Nay, but His two Hands are outstretched, He bestows as He wills. Surely that which has been sent down unto thee from thy Lord will increase many of them in rebellion and disbelief. And we cast enmity and hatred among them till the Day of Resurrection. As often they ignite a flame for war, God extinguishes it. They endeavor to work corruption upon the earth. And God loves not thee workers of corruption." However, the Qur'an also takes a more reconciliatory tone in other lines. An example of this is in 3:113-115: "They are not all alike. Among the People of the Book is an upright community who recite God's signs in the watches of the night, while they prostrate. They believe in God and the Last Day, enjoin right and forbid wrong, and hasten unto good deeds. And they are among the righteous. Whatsoever good they do, they will not be denied it. And God knows the reverent". After reconciling the different descriptions, one can gather the conclusion that some Jews are considered worthy of damnation, while others are righteous and capable of salvation. The transgressions of the "apes and pigs" are not indicative of the entire community.

Islamic eschatology in literature

Ibn al-Nafis wrote of Islamic eschatology in Theologus Autodidactus (circa AD 1270), where he used reason, science, and early Islamic philosophy to explain how he believed al-Qiyamah would unfold, told in the form of a theological fiction novel.

Imran Nazar Hosein wrote numerous books that deal with Islamic eschatology (Ilmu Ākhir al-Zamān – Knowledge of the later days), among which the most famous is Jerusalem in the Qur'an.

Islamic eschatology in 20th and 21st centuries

According to a scholar of Islamic eschatology, Jean-Pierre Filiu, popular Islamic pamphlets and tracts on the End Times have always been in circulation, but “until recently [their] impact on political and theological thinking was practically nil” among Sunnis.

In the early 1980s, when Abdullah Azzam, called on Muslims around the world to join the jihad in Afghanistan, he considered the fight "to be a sign that the end times were imminent". Also around that time, popular Islamic writers, such as Said Ayyub of Egypt, started blaming Islamic decline in the face of the Western world, not on lack of technology and development, but on the forces of the Dajjal.

Al-Qaeda used "apocalyptic predictions in both its internal and external messaging", and its use of "the name Khorasan, a region that includes part of Iran, Central Asia, and Afghanistan, and from which, it is prophesied, the Mahdi will emerge alongside an army bearing black flags", was thought to be a symbol of end times. ISIS has evoked "the apocalyptic tradition much more explicitly". Dabiq, Syria, is a town understood "in some versions" of the eschatological "narrative to be a possible location for the final apocalyptic battle. ISIS captured Dabiq and made it its capital. ISIS also declared its "intent to conquer Constantinople" which was also a part of end times prophesy.

Criticism

Mustafa Akyol criticises the current focus by the Muslim community on apocalypticism and the use of the forces of the Dajjal to explain stagnation in the Muslim world in the past two centuries vis-à-vis the West (and now East Asia). He argues that if supernatural evil is believed to be the cause of the problems of Muslims, then practical solutions such as "science, economic development and liberal democracy" will be ignored in favor of divine intervention. However, Islam is more practical than this, with Muhammad saying that if someone is planting a seed in the final hour of the Earth then they should continue to do so.

History of the city

From Wikipedia, the free encyclopedia

This woodcut shows Nuremberg as a prototype of a flourishing and independent city in the 15th century.

Towns and cities have a long history, although opinions vary on which ancient settlements are truly cities. The benefits of dense settlement included reduced transport costs, exchange of ideas, sharing of natural resources, large local markets, and in some cases amenities such as running water and sewerage. Possible costs would include higher rate of crime, higher mortality rates, higher cost of living, worse pollution, traffic and high commuting times. Cities grow when the benefits of proximity between people and firms are higher than the cost.

Origins

Excavated foundations of Çatalhöyük, Turkey. An Anatolian town dated to 7000 BC.

There is not enough evidence to assert what conditions gave rise to the first cities. Some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces.

The conventional view holds that cities first formed after the Neolithic revolution. The Neolithic revolution brought agriculture, which made denser human populations possible, thereby supporting city development. Whether farming immigrants replaced foragers or foragers began farming is not clear. The increased food production per unit of land supported higher population density and more city-like activities. In his book, Cities and Economic Development, Paul Bairoch takes up this position in his argument that agricultural activity appears necessary before true cities can form.

According to Vere Gordon Childe, for a settlement to qualify as a city, it must have enough surplus of raw materials to support trade and a relatively large population. Bairoch points out that, due to sparse population densities that would have persisted in pre-Neolithic, hunter-gatherer societies, the amount of land that would be required to produce enough food for subsistence and trade for a large population would make it impossible to control the flow of trade. To illustrate this point, Bairoch offers an example: "Western Europe during the pre-Neolithic, [where] the density must have been less than 0.1 person per square kilometre". Using this population density as a base for calculation, and allotting 10% of food towards surplus for trade and assuming that city dwellers do no farming, he calculates that "...to maintain a city with a population of 1,000, and without taking the cost of transport into account, an area of 100,000 square kilometres would have been required. When the cost of transport is taken into account, the figure rises to 200,000 square kilometres ...". Bairoch noted that this is roughly the size of Great Britain. The urban theorist Jane Jacobs suggests that city formation preceded the birth of agriculture, but this view is not widely accepted.

In his book City Economics, Brendan O'Flaherty asserts "Cities could persist—as they have for thousands of years—only if their advantages offset the disadvantages". O'Flaherty illustrates two similar attracting advantages known as increasing returns to scale and economies of scale, which are concepts usually associated with businesses. Their applications are seen in more basic economic systems as well. Increasing returns to scale occurs when "doubling all inputs more than doubles the output [and] an activity has economies of scale if doubling output less than doubles cost".

Similarly, "Are Cities Dying?", a paper by Harvard economist Edward L. Glaeser, delves into similar reasons for city formation: reduced transport costs for goods, people and ideas. Discussing the benefits of proximity, Glaeser claims that if a city is doubled in size, workers get a ten percent increase in earnings. Glaeser furthers his argument by stating that bigger cities do not pay more for equal productivity than in a smaller city, so it is reasonable to assume that workers become more productive if they move to a city twice the size as they initially worked in. The workers do not benefit much from the ten percent wage increase, because it is recycled back into the higher cost of living in a larger city. They do gain other benefits from living in cities, though.

Childe’s ten criteria

The first true towns are sometimes considered large settlements where the inhabitants were no longer simply farmers of the surrounding area, but began to take on specialized occupations, and where trade, food storage and power were centralized. In 1950 Gordon Childe attempted to define a historic city with ten general metrics. These are:

  1. Size and density of the population should be above normal.
  2. Differentiation of the population. Not all residents grow their own food, leading to specialists.
  3. Payment of taxes to a deity or king.
  4. Monumental public buildings.
  5. Those not producing their own food are supported by the king.
  6. Systems of recording and practical science.
  7. A system of writing.
  8. Development of symbolic art.
  9. Trade and import of raw materials.
  10. Specialist craftsmen from outside the kin-group.

This categorisation is descriptive, and it is used as a general touchstone when considering ancient cities, although not all have each of its characteristics.

Ancient times

Cain founding the city of Enoch

The more complex human societies, called the first civilizations emerged around 3000 BC in the river valleys of Mesopotamia, Minoan Crete, India, China, and Egypt. An increase in food production led to the significant growth in human population and the rise of cities. The peoples of Southwest Asia and Egypt laid the foundations of Western civilization, they developed cities and struggled with the problems of organised states as they moved from individual communities to larger territorial units and eventually to empires. Among these early civilizations, Egypt is exceptional for its apparent lack of big cities.

The growth of the population of ancient civilizations, the formation of ancient empires concentrating political power, and the growth in commerce and manufacturing led to ever greater capital cities and centres of commerce and industry, with Alexandria, Antioch and Seleucia of the Hellenistic civilization, Pataliputra (now Patna) in India, Chang'an (now Xi'an) in China, Carthage, ancient Rome, its eastern successor Constantinople (now Istanbul).

The roster of early urban traditions is notable for its diversity. Excavations at early urban sites show that some cities were sparsely populated political capitals, others were trade centers, and still other cities had a primarily religious focus. Some cities had large dense populations, whereas others carried out urban activities in the realms of politics or religion without having large associated populations. Theories that attempt to explain ancient urbanism by a single factor, such as economic benefit, fail to capture the range of variation documented by archaeologists.

Mediterranean and Mesopotamia

The "Great Colonnade" marks the cardo maximus of Apamea, Syria.

The earliest known city is Çatalhöyük, a settlement of some 10000 people in southern Anatolia that existed from approximately 7100 BC to 5700 BC. Hunting, agriculture and animal domestication all played a role in the society of Çatalhöyük.

Ancient Mesopotamia, the area of the Tigris and Euphrates within modern day Iraq and Syria, was home to numerous cities by the third millennium BC. These cities formed the basis of the Sumerian and subsequent cultures. Cities such as Jericho, Uruk, Ur, Nineveh, and Babylon, made legendary by the Bible, have been located and excavated, while others such as Damascus and Jerusalem have been continuously populated.

The Phoenician trading empire, flourishing around the turn of the first millennium BC, encompassed numerous cities extending from Tyre, Cydon, and Byblos, across the Mediterranean to Carthage (in modern Tunisia) and Cádiz (in modern Spain). The name of Melqart, an important Phoenician deity, comes from M-L-K and Q-R-T, meaning "king" and "city".

Beginning in the early first millennium, independent city-states in Greece began to flourish, evolving the notion of citizenship, becoming in the process the archetype of the free city, the polis. The agora, meaning "gathering place" or "assembly", was the center of athletic, artistic, spiritual and political life of the polis. These Greek city-states reached great levels of prosperity that resulted in an unprecedented cultural boom, that of classical Greece, expressed in architecture, drama, science, mathematics and philosophy, and nurtured in Athens under a democratic government. The Greek Hippodamus of Miletus (c. 407 BC) has been dubbed the "Father of City Planning" for his design of Miletus; the Hippodamian, or grid plan, was the basis for subsequent Greek and Roman cities. In the 4th century BC, Alexander the Great commissioned Dinocrates of Rhodes to lay out his new city of Alexandria, the grandest example of idealized urban planning of the ancient Mediterranean world, where the city's regularity was facilitated by its level site near a mouth of the Nile.

The rise of Rome again shifted the locus of political power, resulting in economic and demographic gain for the city of Rome itself, and a new political regime in the form of the Roman Empire. Rome founded many cities (coloniae), characteristically imposing a grid pattern made of north–south cardines and east–west decumani. The intersection of the cardo maximus and the decumanus maximus marked the origin of the city grid. Following these standard plans, Rome founded hundreds of cities and exerted substantial influence toward urbanizing the Mediterranean. In the process, Rome developed sanitation, public housing, public buildings and the forum. In the late Roman Empire political power was increasingly held by bishops of the Christian Church.

Asia

The Indus Valley Civilization and ancient China are two other areas with major indigenous urban traditions. Among the early Old World cities, Mohenjo-daro of the Indus Valley Civilization in present-day Pakistan, existing from about 2600 BC, was one of the largest, with a population of 50,000 or more and a sophisticated sanitation system.

China's planned cities date to the turn of the second millennium BC. City-states emerging at this time used geomancy to locate and plan cities, orienting their walls to cardinal points. Symbolic cities were constructed as celestial microcosms, with the central point corresponding to the pole star representing harmony and connection between the earthly and other realms. In Chang'an the imperial palace lay to the north, facing south, absorbing the light of the sun, and royalty slept with their heads to the north and their feet to the south. Next came the Imperial City, and then the people's city, divided into eastern and western halves.

Sub-Saharan Africa

Agriculture was practiced in sub-Saharan Africa since the third millennium BC. Because of this, cities could develop as centers of non-agricultural activity, well before the influence of Arab urban culture. One of the oldest sites documented thus far, Jenné-Jeno in what is today Mali, has been dated to the third century BC. According to Roderick and Susan McIntosh, Jenné-Jeno did not fit into traditional Western conceptions of urbanity as it lacked monumental architecture and a distinctive elite social class, but it should indeed be considered a city based on a functional redefinition of urban development. In particular, Jenné-Jeno featured settlement mounds arranged according to a horizontal, rather than vertical, power hierarchy, and served as a center of specialized production and exhibited functional interdependence with the surrounding hinterland. Archaeological evidence from Jenné-Jeno, specifically the presence of non-West African glass beads dated from the third century BC to the fourth century AD, indicates that pre-Arabic trade contacts probably existed between Jenné-Jeno and North Africa. Additionally, other early urban centers in sub-Saharan Africa, dated to around 500 AD, include Awdaghust, Kumbi-Saleh the ancient capital of Ghana, and Maranda a center located on a trade rout between Egypt and Gao.

Americas

The Avenue of the Dead in Teotihuacan originates with the Pyramid of the Moon, forming the basis of the city grid.

In the ancient Americas, early urban traditions developed in the Andes and Mesoamerica. In the Andes, the first urban centers developed in the Norte Chico civilization (also Caral or Caral-Supe civilization), Chavin and Moche cultures, followed by major cities in the Huari, Chimu and Inca cultures. The Norte Chico civilization included as many as 30 major population centers in what is now the Norte Chico region of north-central coastal Peru. It is the oldest known civilization in the Americas, flourishing between the 30th century BC and the 18th century BC. Mesoamerica saw the rise of early urbanism in several cultural regions, including the Preclassic Maya, the Zapotec of Oaxaca, and Teotihuacan in central Mexico. Later cultures such as the Aztec drew on these earlier urban traditions.

Teotihuacan, flourishing from 200 BC to AD 750, was the largest American city of the pre-Columbian era, possibly reaching a population of 125,000 in AD 200. The city's grid plan originated with the "Avenue of the Dead", connecting the Temple of the Feathered Serpent and the Pyramid of the Moon. Beyond its ceremonial center the city featured religious buildings (23 temple complexes) and myriad workshops. Although its religious system was clearly expansive and significant, details of its political and economic functioning remain matters of speculation.

Middle Ages

The Round city of Baghdad, the capital of Iraq

In the remnants of the Roman Empire, cities of late antiquity at first gained independence, but lost their population and their importance, starting in Roman Britain and Germania. The locus of power in the West shifted to Constantinople and to the ascendant Islamic civilization with its major cities Baghdad, Cairo, and Córdoba.

From the 9th through the end of the 12th century, Constantinople, capital of the Byzantine Empire, was the largest and wealthiest city in Europe, with a population approaching 1 million. Following the Byzantine–Ottoman wars and other conflicts, the Ottoman Empire gained control over many cities in the Mediterranean area, including Constantinople in 1453.

During the European Middle Ages, a town was as much a political entity as a collection of houses. City residence brought freedom from customary rural obligations to lord and community: "Stadtluft macht frei" ("City air makes you free") was a saying in Germany. In Continental Europe cities with a legislature of their own were not unheard of, the laws for towns as a rule other than for the countryside, the lord of a town often being another than for surrounding land. In the Holy Roman Empire, some cities had no other lord than the emperor. Some planned towns were created, in Britain by King Edward I to colonize Wales and in France, bastides, fortified cities designed on a regular plan.

By the thirteenth and fourteenth centuries some cities become powerful states, taking surrounding areas under their control or establishing extensive maritime empires. In Italy medieval communes developed into city-states including the Republic of Venice and the Republic of Genoa. These cities, with populations in the tens of thousands, amassed enormous wealth by means of extensive trade in eastern luxury goods such as spices and silk, as well as iron, timber, and slaves. Venice introduced the ghetto, a specially regulated neighborhood for Jews only. In Northern Europe, cities including Lübeck and Bruges formed the Hanseatic League for collective defense and commerce. Their power was later challenged and eclipsed by the Dutch commercial cities of Ghent, Ypres, and Amsterdam. (City rights were granted by nobility.) The city's central function was commerce, enabled by waterways and ports; the cities themselves were heavily fortified with walls and sometimes moats.

Similar phenomena existed elsewhere, as in the case of Sakai, which enjoyed a considerable autonomy in late medieval Japan.

In the first millennium AD, an urban tradition developed in the Khmer region of Cambodia, where Angkor grew into one of the largest cities (in area) of the world. The closest rival to Angkor, the Mayan city of Tikal in Guatemala, was between 100 and 150 square kilometres (39 and 58 sq mi) in total size. Although its population remains a topic of research and debate, newly identified agricultural systems in the Angkor area may have supported up to one million people.

Palmanova, Italy, constructed in 1593 according to the defensive ideal of the star fort, today retains its distinctive geometry.
 
Gdańsk in the 17th century

While the city-states, or poleis, of the Mediterranean and Baltic Sea languished from the 16th century, Western Europe's larger capitals grew again as commercial hubs, especially following the emergence of an Atlantic trade. By the early 19th century, London had become the largest city in the world with a population of over a million, while Paris rivaled the well-developed regionally traditional capital cities of Baghdad, Beijing, Istanbul and Kyoto. Bastion forts arose in an attempt to make cities defensible against strengthening military firepower.

The Aztec city of Tenochtitlan, in present-day Mexico, had an estimated population between 200,000 and 300,000 when the Spanish conquistador Hernán Cortés arrived in 1519. During the Spanish colonization of the Americas the old Roman city concept was extensively used. Cities were founded in the middle of the newly conquered territories, and were bound to several laws about administration, finances and urbanism.

Most towns remained small, so that in 1500 only some two dozen places in the world contained more than 100,000 inhabitants. As late as 1700, there were fewer than forty, a figure that rose to 300 in 1900.

Industrial revolution

Glasgow slum in 1871

The growth of modern industry from the late 18th century onward led to massive urbanization and the rise of new great cities, first in Europe and then in other regions, as new opportunities brought huge numbers of migrants from rural communities into urban areas. England led the way as London became the capital of a world empire and cities across the country grew in locations strategic for manufacturing. In the United States from 1860 to 1910, the introduction of railroads reduced transportation costs, and large manufacturing centers began to emerge, fueling migration from rural to city areas.

Industrialized cities became deadly places to live, due to health problems resulting from overcrowding, occupational hazards of industry, contaminated water and air, poor sanitation, and communicable diseases such as typhoid and cholera. Factories and slums emerged as regular features of the urban landscape.

Infrastructure

The 19th century saw the rise of public transportation, such as horsebuses, followed by horse trams. At the end of the 19th century, electric urban rail transport (including trams and rapid transit) began to replace them, later completed with buses and other motor vehicles.

Street lights were uncommon until gas lighting became widespread in Europe in the early 19th century. Fuel gas was also used for heating and cooking. From the 1880s, electrification began, making electricity the main energy medium in cities until present day.

Modern water supply networks began to expand during the 19th century.

20th century

Growth of cities continued through the twentieth century and increased dramatically in the Third World (including India, China, and Africa), due to industrialization, active promotion of urbanization, and other factors.

Urban planning became widespread and professionalized. At the turn of the century, the "garden city" model became the icon of a self-contained, comprehensively designed, residential and commercial settlement. Professional urban planners appeared in large numbers, not only to design cities, but to provide technical expertise to their administration.

Cities in the great depression of the 1930s, especially those with a base in heavy industry, were hard hit by unemployment. In the U.S. urbanization rate increased forty to eighty percent during 1900–1990. Today the world's population is slightly over half urban, and continues to urbanize, with roughly a million people moving into cities every 24 hours worldwide.

During the 20th century, car ownership has increased steady, parallel with suburban sprawl, highways and other development for the car. Awareness of ecology in the mid-20th century created the environmental movement, which has addressed the need for sustainable development.

In the second half of the twentieth century, deindustrialization (or "economic restructuring") in the West led to poverty, homelessness, and urban decay in formerly prosperous cities. America's "Steel Belt" became a "Rust Belt" and cities such as Detroit, Michigan, and Gary, Indiana began to shrink, contrary to the global trend of massive urban expansion. Under the Great Leap Forward and subsequent five-year plans continuing today, the People's Republic of China has undergone concomitant urbanization and industrialization to become the world's leading manufacturer.

21st century

There is a debate about whether technology and instantaneous communications are making cities obsolete, or reinforcing the importance of big cities as centres of the knowledge economy. Knowledge-based development of cities, globalization of innovation networks, and broadband services are driving forces of a new city planning paradigm towards smart cities that use technology and communication to create more efficient agglomerations in terms of competitiveness, innovation, environment, energy, utilities, governance, and delivery of services to the citizen. Some companies are building brand new masterplanned cities from scratch on greenfield sites.
