Al-Adab Al-Mufrad #206

Ibn 'Umar reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "All of you are shepherds and each of you is responsible for his flock. The amir of a people is a shepherd and he is responsible for his flock. A man is the shepherd of the people of his house and he is responsible for his flock. A man's slave is the shepherd of his master's property and he is responsible for it. Each of you is a shepherd and each of you is responsible for his flock."
