The Messenger of Allah (ﷺ) as saying: Each of you is a shepherd and each of you is responsible for his flock. The amir (ruler) who is over the people is a shepherd and is responsible for his flock; a man is a shepherd in charge of the inhabitants of his household and he is responsible for his flock; a woman is a shepherdess in charge of her husband's house and children and she is responsible for them; and a man's slave is a shepherd in charge of his master's property and he is responsible for it. So each of you is a shepherd and each of you is responsible for his flock.

The Messenger of Allah (ﷺ) said to me: 'Abdul al-Rahman b. Samurah, do not ask for the position of commander, for if you are given it after asking you will be left to discharge it yourself, but if you are given it without asking you will be helped to discharge it.

I went along with two men to see the Prophet (ﷺ). One of them recited tashahhud and said: We have come to you so that you may employ us for your work. The other also said the same thing. He (the Prophet) replied: The most faithless of you in our eyes is the one who asked for it (responsible post). Abu Musa then apologized to the Prophet (ﷺ) and said: I did not know why they came to you. He did not employ them for anything until he died.

The Prophet (ﷺ) appointed Ubn Umm Makthum as a governor of Medina (in his absence) twice.

The Messenger of Allah (ﷺ) said: When Allah has a good purpose for a ruler, He appoints for him a sincere minister who reminds him if he forgets and helps him if he remembers; but when Allah has a different purpose from that for him. He appoints for him an evil minister who does not remind him if he forgets and does not help him if he remembers.
