Abu Hurairah, May Allah be pleased with him, reported:The Messenger of Allah, may the peace and blessings of Allah be upon him, said, "Hasten to do good deeds before you are overtaken by one of the seven afflictions." Then (giving a warning) he said, "Are you waiting for such poverty which will make you unmindful of devotion; or prosperity which will make you corrupt, or disease as will disable you, or such senility as will make you mentally unstable, or sudden death, or Ad-Dajjal who is the worst expected absent, or the Hour, and the Hour will be most grievous and most bitter"
