Kitab al-Fitan · Nu'aym ibn Hammad

I have heard that the Mahdi lives forty years, then dies in his bed, then a man emerges from Qahtan with pierced ears, following the manner of the Mahdi, he lives for twenty years, then he dies with weapons, then a man from the family of the Prophet (may Allah’s prayers and peace be upon him) emerges, a Mahdi of good character, who conquers the city of Caesar, and he is the last prince from the nation of Muhammad (may Allah’s prayers and peace be upon him), then the Dajjal will emerge in his time, and Jesus, the son of Mary, peace be upon him, will descend in his time.

At the hands of that Yamani Caliph, through whom Constantinople and Rome were conquered, the Dajjal will emerge, and in his time Jesus, son of Mary (peace be upon him), will descend. The Battle of India will take place at his hands, and he is from Banu Hashim.
