Chapter 20: Tribute, Spoils, and Rulership (Kitab Al-Kharaj, Wal-Fai' Wal-Imarah)
Narrated 'Abdullah bin 'Umar: 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.
