Al-Adab Al-Mufrad #579

'Abda ibn Hazn said, "The people of camels and the people of sheep vied with one another for glory. The Prophet, may Allah bless him and grant him peace, said, 'Musa was sent, and he was a shepherd. Da'ud was sent, and he was a shepherd. I was sent, and I used to herd sheep for my people at Ajyad.'"
