“Hasten to perform righteous deeds before seven things: are you waiting for poverty which will make you forget everything, or wealth which will make you transgress, or a disease which will corrupt you, or old age which will render you feeble-minded, or sudden death which will destroy you, or the Dajjal who is the worst awaited absent one, or are you waiting for the Hour (Day of Judgment), for the Hour is most grievous and bitter.”
