Riyad as-Salihin #1794

Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) 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 poverty which will make you unmindful of devotion, or prosperity which will make you corrupt, or a disease which will disable you, or senility which will make you mentally unstable, or sudden death which will take you all of a sudden, or Ad-Dajjal who is the worst expected, or the Hour; and the Hour will be most grievous and most bitter.".
