Musannaf Ibn Abi Shaybah

Narrated from Hazrat Abu Bakrah, he said that the Messenger of Allah (peace and blessings be upon him) mentioned a land called Basrah or Basirah, on one side of which there is a river called Dijlah (Tigris), with many date palms. There, the Banu Qantura will descend (who are referred to as the Turks, and according to the statement of Hakim, by this is meant the Christians of Rome). People will be divided into three groups: one group will join their origin and will be destroyed; the second group will take their souls and disbelieve; and the third group will leave their children behind and fight. Their slain will be martyrs, and Allah Almighty will grant victory to those who remain.
