Sayyiduna Abdur Rahman bin Samurah رضي الله عنه narrates that the Messenger of Allah صلى الله عليه وآله وسلم said to me: O Abdur Rahman! Do not seek leadership or responsibility. If leadership is given to you after you have sought it, you will be left to it (without divine help), but if it is given to you without your seeking it, you will be helped in it. And when you swear an oath about something, then later realize that doing otherwise is better, then do what is better and offer expiation for your oath.
