Kitab al-Fitan · Nu'aym ibn Hammad

The Mahdi will descend in Bayt al-Maqdis, then there will be caliphs from his family after him, their term will be prolonged, and they will be arrogant until the people pray against the Banu Abbas and the Banu Umayyad from what they receive from them.

A caliph from the Banu Hashim will descend on Jerusalem and fill the earth with justice. He will build Jerusalem a building that has never been built before. He will rule for forty years. The Roman truce will be under his control for seven years remaining in his caliphate. Then they will betray him, then they will gather for him in the depths, and he will die there in grief. Then a man from the Banu Hashim will follow after him, then their defeat will occur, and the conquest of Constantinople will be on his hands. Then he will go to Rome and conquer it, extracting its treasures and the table of Suleiman ibn David, peace be upon them, then returns to Jerusalem and descends there. The Dajjal will emerge in his time, and Jesus, son of Mary (peace be upon him), will descend and pray behind him.

A man from among us will follow at the end of time for forty years, and the epics will be for seven years remaining in his caliphate, then he will die in the depths of grief, then a man among them will follow him with two moles, and on his hands will be the conquest that day, meaning the conquest of the Romans in the depths.
