From Sahih Muslim (Hadith 7277):
Abu Huraira reported Allah's Messenger (ﷺ) as saying:Iraq would withhold its dirhams and qafiz; Syria would withhold its mudd and dinar and Egypt would withhold its irdab and dinar and you would recoil to that position from where you started and you would recoil to that position from where you started and you would recoil to that position from where you started, the flesh and blood of Abu Huraira would bear testimony to it
