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."

حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنَا عَمْرُو بْنُ يَحْيَى بْنِ سَعِيدٍ الْقُرَشِيُّ، عَنْ جَدِّهِ، سَعِيدِ بْنِ أَبِي أُحَيْحَةَ عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " مَا بَعَثَ اللَّهُ نَبِيًّا إِلاَّ رَاعِيَ غَنَمٍ " . قَالَ لَهُ أَصْحَابُهُ وَأَنْتَ يَا رَسُولَ اللَّهِ . قَالَ " وَأَنَا كُنْتُ أَرْعَاهَا لأَهْلِ مَكَّةَ بِالْقَرَارِيطِ " . قَالَ سُوَيْدٌ يَعْنِي كُلُّ شَاةٍ بِقِيرَاطٍ .
