Sayyiduna Mustawrid Fahri (may Allah be pleased with him) said to Sayyiduna Amr ibn al-As (may Allah be pleased with him): At the time when the Day of Judgment is established, the number of Romans will be the greatest. Sayyiduna Amr ibn al-As (may Allah be pleased with him) said to him: Consider carefully, what are you saying? He replied: I am telling you exactly what I heard from the Messenger of Allah (peace and blessings be upon him). Upon hearing this, Sayyiduna Amr (may Allah be pleased with him) said: If you are saying this, then the reason is that the Romans possess these four qualities: (1) If they flee from the battlefield, they return very quickly to launch a (retaliatory) attack, (2) they are much better than others in regard to the rights of the poor, needy, and weak, (3) they prove to be the most courageous at the time of battle, and (4) these people are the foremost in restraining the oppression of kings.

Sayyiduna Mustawrid (may Allah be pleased with him) says: I was with Sayyiduna Amr ibn al-As (may Allah be pleased with him), and I said to him that the Messenger of Allah (peace and blessings be upon him) said: "Your greatest opponents are the Romans; their end will be with the Day of Resurrection." Sayyiduna Amr (may Allah be pleased with him) said to this: "Did I not forbid you from narrating such ahadith?"

It is narrated from Asir bin Jabir, he says: Once a red wind blew in Kufa. An ordinary man, who had no particular importance, said to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Day of Judgment has come. Sayyiduna Ibn Mas'ud (may Allah be pleased with him), who was reclining at first, sat up upon hearing this and said: The Day of Judgment will not be established until inheritance is distributed and people rejoice over war booty. The enemies of Islam will gather against the people of Islam, and the people of Islam will gather against them. While saying this, he pointed towards Syria. I said: Do you mean the Romans? He said: Yes. At that time, there will be a severe battle. The Muslims will pledge to fight to the death, that only the victors will return. So they will fight until night falls between them and their enemies, and both the Muslims and the Romans will return, and none of them will be victorious or dominant, and thus the pledge will end. Then the Muslims will again pledge to fight to the death, that only the victors will return. So they will fight until night falls between them and their enemies, and both will return in such a state that none of them will be victorious, and thus this pledge will also end. This time too, the Muslims will pledge to fight to the death, that only with victory will they return. So they will fight until evening comes, and both will return without victory, and the pledge will end. When the fourth day comes, the remaining people of Islam will also rise to face the enemy. Allah Almighty will impose defeat upon them. They will fight such a battle as has never been seen before. (So many heaps of corpses will be piled up that) if a bird flies from one side, it will die before it can cross over them. The situation will be such that if a man counts his hundred sons, only one will survive. In such circumstances, what joy will there be in war booty, and what inheritance will be distributed? People will be in such a state when an even greater news will be announced, and that is that a caller will cry out that the Dajjal has reached among your children left behind. Upon hearing this, they will throw away all things and turn their attention there, and will send a detachment of ten horsemen. The Messenger of Allah (peace and blessings be upon him) said: I know the names of those horsemen, their fathers and grandfathers, and even the colors of their horses. They will be the best horsemen on the face of the earth at that time.

Sayyiduna Abu Bakrah narrates that the Noble Prophet (peace and blessings be upon him) mentioned the land of Basrah and said: On one side of it is a river called Dijlah (Tigris), and there are many date palms there. The Banu Qantura (i.e., the Turks) will come and settle there, and the Muslims will be divided into three groups: one group will join their origin (i.e., will become occupied with their fields and cattle), these people will be destroyed; the second group will remain aloof, these people will become disbelievers; and one group will leave their wives and children behind and will fight, their slain will be martyrs, then Allah Almighty will grant victory to the remaining ones. Once, while narrating this hadith, Yazid bin Harun was uncertain whether it was Basirah or Basrah.

(Second chain) It is narrated from Sayyiduna Abu Bakrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "You will surely settle on the land of Basrah or Basirah by the bank of the river Dijlah (Tigris), ... then he mentioned as in the previous hadith. The common people said: By Banu Qantura are meant the Turks."

(Third chain) Abdullah bin Abu Bakrah says: My father narrated to me in that mosque of Basra that the Messenger of Allah, peace and blessings be upon him, said: A group of my Ummah will surely settle in the land called Basra, there they will be great in number and there will be an abundance of dates. Then the Banu Qantura, whose faces will be flat and eyes small, will come and camp at the bridge of the Tigris. Thereupon, the Muslims will be divided into three groups: one group will hold onto the tails of camels and head towards the villages; these people will be destroyed. The second group will remain absorbed in their own state; they will become disbelievers. Both these groups will be equal in terms of their end. The third group will leave their families behind and fight against the disbelievers; their slain will be martyrs. Then Allah, the Exalted, will grant victory to the remaining people of this group.

It is narrated from Sayyiduna Buraidah Aslami (may Allah be pleased with him), he says: I was sitting with the Noble Prophet (peace and blessings be upon him) when I heard him say: A people whose faces will be broad and their eyes small, as if their faces are as broad as shields (he said this three times), this people will drive my Ummah towards the Arabian Peninsula. Whoever flees from their first encounter will be saved, in the second encounter some will be killed and some will be saved, and in the third time, they will wipe out even those who remain. The Companions asked: O Messenger of Allah! Who will these people be? He said: They will be the Turks. He (peace and blessings be upon him) further said: By Him in Whose hand is my soul! They will tie their horses to the pillars of the Muslims’ mosques. Sayyiduna Abdullah bin Buraidah, after hearing this hadith of the Noble Prophet (peace and blessings be upon him), used to always keep two or three camels, travel provisions, and water skins ready in order to escape from the trial of the Turkish rulers.

It is narrated from Sayyiduna Abu Huraira, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: The Hour will not be established until the river Euphrates uncovers a mountain of gold, over which people will fight so much that out of every hundred, ninety-nine will be killed in that battle. Dear son! If you find yourself in such circumstances, do not be among those who fight.

(Second chain) It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "The time is near when the river Euphrates will uncover a mountain of gold, and people will fight over it to such an extent that out of every ten men, nine will be killed and only one will remain."

It is narrated from Sayyiduna Bishr bin Suhaim (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "Constantinople will certainly be conquered; its commander will be the best commander and that army will be the best army." Abdullah says: Maslamah bin Abdul Malik called me and asked me about this, so I narrated this hadith to him, and because of this, he launched an expedition against Constantinople.
