The Messenger of Allah ﷺ said, "Iraq will withhold its dirham and its qafiz, Syria will withhold its mudd and its Dinar, and Egypt will withhold its irdabb and its Dinar. You will return to where you began, you will return to where you began, you will return to where you began. The flesh and blood of Abu Hurairah bear witness to this."
قال رسول الله ﷺ: منعت العراق درهمها وقفيزها، ومنعت الشام مديها ودينارها، ومنعت مصر إردبها ودينارها، وعدتم من حيث بدأتم، وعدتم من حيث بدأتم، وعدتم من حيث بدأتم، شهد على ذلك لحم أبي هريرة ودمه.
Muslim narrated it in the Book of Tribulations and Signs of the Hour (2896:33) via Yahya bin Adam bin Sulayman, the freed slave of Khalid bin Khalid, who said, Zuhayr narrated to us, from Suhayl bin Abu Salih, from his father, from Abu Hurairah, and he related it.
