Kitab al-Fitan · Nu'aym ibn Hammad

Rushdin told us, on the authority of Ibn Lahi’ah, on the authority of Abdul Aziz bin Salih, on the authority of Hudhayfah, he said: “The temptations after the Messenger of Allah ﷺ until the Hour comes, there will be four temptations: the first is five, the second is twenty, the third is twenty, and the fourth is the Dajjal.” He said.

Al-Walid said, and I read to Daniel, he said: All the affairs of this nation after its Prophet Muhammad (may Allah’s prayers and peace be upon him) until Jesus are two hundred and seventy-four years. The Umayyads had eighty years of that, and the rulers, who were twelve, had a hundred years. The tyrants would rule for forty years, and the people would remain without anyone for seven years. The Dajjal would emerge for seven years, and Jesus, the son of Mary, peace be upon him, would emerge and be forty years. He said

Seven years elapsed between the conquest of Constantinople and the emergence of the Dajjal
