Kitab al-Fitan · Nu'aym ibn Hammad

A black flag of Banu Abbas will emerge, then another black flag will emerge from Khorasan. Their hoods are black and their clothes are white. At the front of them is a man called Shuaib bin Saleh bin Shuaib from Tamim. They will defeat the companions of the Sufyani until he descends on Jerusalem. The Mahdi will establish his authority and extend to him three hundred men from the Levant. There will be seventy-two months between his emergence and the handing over of authority to the Mahdi.

Abdullah bin Marwan told us, on the authority of Artat, on the authority of Tabi’, on the authority of Ka’b, who said: “When the millstone of Banu Abbas has turned, and the owners of the black banners tie their horses to the olive trees of the Levant, and Allah destroys for them the red-haired man, and kills him and all of his household at their hands, until there is no Umayyad among them left except one who flees or disappears, and the two palms fall: Banu Ja’far and Banu Abbas, and the son of the liver-eater sits on the pulpit of Damascus, and the Berbers go out to The navel of Syria is the sign of the emergence of the Mahdi.”
