War will not lay down its burdens until there are six signs

It is narrated from Sayyiduna Awf bin Malik al-Ashja'i (may Allah be pleased with him) that on the occasion of a conquest he came to the Messenger of Allah (peace and blessings be upon him), greeted him (peace and blessings be upon him) with salam and said: O Messenger of Allah! Congratulations to you; Allah has honoured your victory and made your religion prevail, and war has laid down its burdens (its weapons). At that time the Messenger of Allah (peace and blessings be upon him) was seated in a leather tent (a dome-shaped tent). He (peace and blessings be upon him) said: "O Awf! Come inside." He asked: Shall I come in wholly or partly? He (peace and blessings be upon him) said: "Come in wholly." Then he (peace and blessings be upon him) said: "War will not lay down its burdens until six (signs) have appeared: the first of them is my death." Hearing this, Awf began to weep, and the Messenger of Allah (peace and blessings be upon him) said: "Say: This is the first. The second: the conquest of Bayt al-Maqdis (Jerusalem). The third: a tribulation will befall the people like the disease of sheep ('uqas), (killing suddenly). The fourth: a tribulation from which no household among the people will be spared without its effect entering it. The fifth: a boy from the children of kings will be born among Banu al-Asfar (the Romans). He will grow in a day as much as an ordinary child grows in a week, in a week as much as an ordinary child grows in a month, and in a month as much as an ordinary child grows in a whole year. When he reaches twelve years of age, they will make him their king. Then he will stand among them and say: How long will these people (the Muslims) prevail over the best of our lands?! I intend to march against them with an army and drive them out of it. So the orators will stand up and endorse his opinion. He will order ships to be built on the islands and on land, then he will load fighters onto them and land them between Antioch and al-Arish." Ibn Shurayh said: I heard someone say: They will be under twelve banners (ghayayah), and under every banner there will be twelve thousand soldiers. The Muslims will gather to their leader in Bayt al-Maqdis, and they will agree in their opinion to march towards the City of the Messenger (Madinah) until their outposts reach al-Sarh and Khaybar. Ibn Abi Ja'far said that the Messenger of Allah (peace and blessings be upon him) said: "They will drive my Ummah out of the places where desert plants (shih) grow." Al-Harith bin Yazid said: They (the Romans) will remain there; a third of the Muslims will flee (in fear), a third will be martyred, and Allah, the Mighty and Majestic, will grant defeat upon them through the third who are steadfast. Khalid bin Yazid said: By Allah! On that day the Muslims will fight with their swords and spears and will pursue them until they reach the narrow passage near Constantinople. They will find that its water has dried up, so they will cross over to the city (Constantinople) and encamp there. Then Allah Almighty will bring down their walls through the takbir (the cry of Allahu Akbar), and the Muslims will prevail over them and will divide the spoils by the shield-full. Abu Qabil said: While they are in this state, suddenly a rider will come and say: You are here while the Dajjal has come behind you among your families; yet this will be a false report. So those who had heard the words of the people of knowledge will hold firm to their success, and the rest will disperse. The Muslims will be building mosques in Constantinople and waging jihad beyond it until the Dajjal emerges, and this will be the sixth sign.
This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Kurayb (the freed slave of Ibn Abbas) that he was sitting with Sayyiduna Ibn Abbas and Sayyiduna Ibn al-Zubayr (may Allah be pleased with them) among a group of people, when Sayyiduna Abu Hurayrah (may Allah be pleased with him) came in and said: "Die, all of you!" At this Ibn al-Zubayr (may Allah be pleased with him) said: O Abu Hurayrah! (What are you saying?) The religion is established, jihad continues, and the prayer, zakah, Hajj and the fasting of Ramadan are (all) present. Abu Hurayrah (may Allah be pleased with him) said: (What I mean is) that you should die before that time comes when the doer of good will be unable to increase his good, and the wrongdoer will be unable to turn back from his wrongdoing (that is, conditions will become so corrupted by the abundance of tribulations).

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he said: "There has never been a state of truth in which Adam (truth) was not given the upper hand over Iblis (falsehood), nor a state of falsehood in which Iblis was not given the upper hand over Adam. Iblis was commanded to prostrate but he disobeyed, so Adam was given the upper hand over him, until, when one (of the sons of Adam) killed the other, Iblis was given the upper hand over him. And soon tribulations will arise: a particular tribulation and a general tribulation, then a particular tribulation and then a general tribulation." It was said: O Commander of the Believers! What is meant by the particular and the general tribulation? He said: "(A time will come when) there will be two imams (leaders): one an imam of truth and the other of falsehood. (People's state will be that) some will turn from truth to falsehood and some from falsehood to truth; this is the 'particular tribulation' (which concerns the beliefs of individuals). Then there will be two imams: one of truth and the other of falsehood, and (the whole society) will begin to turn from truth to falsehood and from falsehood to truth; this is the 'general tribulation' (which will envelop the entire nation)."
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim) (because its narrator al-Waddah is none other than Abu Awanah), but they did not record it.
