It was narrated from Abu Hurairah that the Messenger of Allah ﷺ said:
"Allah has not sent any Prophet but he was a shepherd." His Companions said to him: "Even you, O Messenger of Allah?" He said: "Even me I used to tend the sheep of the people of Makkah for a few Qirats." (One of the narrators) Suwaid said: " Meaning one Qirat for every sheep."
