کتاب الفتن · نُعیم بن حماد

Abdullah said that five signs have (become things) of the past (and have proved the truth of the Holy Prophet):(Enveloping) by the smoke, inevitable (punishment to the Meccans at Badr), (the victory of) Rome, (violent) seizing (of the Meccans at Badr) and (the splitting up of) the Moon

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)
