Abu Hurairah رضي الله عنه related that a bedouin asked the Messenger of Allah صلى الله عليه وسلم, “When is the Hour?” He صلى الله عليه وسلم said, “When the trust will be lost, then wait for the Hour.” He said, “O Messenger of Allah, and how will it be lost?” He صلى الله عليه وسلم said, “When the affair will be entrusted to those who do not deserve it, then wait for the Hour.”
