Mukhtasar Bukhari

Sayyiduna Abdur Rahman bin Samurah (may Allah be pleased with him) says that the Prophet Muhammad (peace and blessings of Allah be upon him) said to me: "O Abdur Rahman bin Samurah! Do not ask for authority, because if it is given to you as a result of your asking, then you will be left to it (without divine help), but if it is given to you without your asking, then you will be helped in it (by Allah). And when you swear an oath (not to do something) and then you see that it is better to do it, then offer expiation for your oath and do that (better) thing."
