Abū Bakr ibn Abi Maryam reported that he heard the Messenger of Allah say: "A time is certainly coming over mankind in which there will be nothing (left) that will be of use (or benefit) save a Dinār (ie, a gold coin) and a Dirham (ie, a silver coin). [This prophecy clearly anticipates the eventual collapse of the fraudulent monetary system now functioning around the world.] (Musnad, Ahmad)
