کتاب الفتن · نُعیم بن حماد

Naim told us, then Ibn Aliyah, Awf told me, on the authority of Abu al-Mughirah al-Qawwas, on the authority of Abdullah bin Amr, he said: “The epics of the people are five, two have passed, and three have passed in this nation: the epic of the Turks, the epic of the Romans, and the epic of the Dajjal. There is no epic after the Dajjal’s epic.”

The Romans emerge in the Great Epic, and with them are the Turks, Burjan, and Saqlaba

Abu Nadra reported:"We were in the company of Jabir b. 'Abdullah that he said it may happen that the people of Iraq may not send their qafiz and dirhams (their measures of food stuff and their money). We said: Who would be responsible for it? He said: The non-Arabs would prevent them. He again said: There is the possibility that the people of Syria may not send their dinars and mudds. We said: Who would be responsible for it? He said this prevention would be made by the Romans. He (Jabir b. Abdullah) kept quiet for a while and then reported Allah's Messenger (ﷺ) having said there would be a caliph in the last (period) of my Ummah who would freely give handfuls of wealth to the people without counting it. I said to Abu Nadra and Abu al-'Ala: Do you mean 'Umar b. 'Abd al-Aziz? They said: No (he would be Imam Mahdi)
