Narrated 'Abdur-Rahman bin Samurah:
That the Messenger of Allah (ﷺ) said: O 'Abdur-Rahman! Do not ask for a position of leadership, for if you receive it due to asking, you will be left alone with it, and if you receive it without asking, then you will be aided in it. And if you take an oath and you see that something else is better than it, then do what is better, and make an atonement for your oath.
