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)
Abu Sa'id reported that Allah's Messenger (may peace he upon him) I said:There would be amongst your caliphs a caliph who would give handfuls of wealth to the people, but would not count it. In the narration transmitted on the authority of Ibn Hujr, there is a slight variation of wording
Abu Sa'id and Jabir b. Abdullah reported that Allah's Messenger (ﷺ) said:There would be in the last phase of the time a caliph who would distribute wealth but would not count
Abu Sa`id Khudri reported:One who is better than I informed me, that Allah's Messenger (ﷺ) said to `Ammar as he was digging the ditch (on the ocassion of the Battle of the Ditch) wiping over his head: O son of Summayya, you will be involved in trouble and a group of the rebels would kill you
This hadith has been transmitted on the same authority but with this variation that the hadith transmitted on the authority of Nabra (the words are):One who is better than I informed me, and he was Abu Qatada, and in the hadith transmitted on the authority of Khalid instead of the word 'bu'us' there is 'wayys' or 'ya wayys', i.e., " how sad it is
