Sunan Ibn Majah, Book 12, Hadith 2232 (In-Book) ⓘ
It was narrated from Abu Hurairah that the Messenger of Allah 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." (Sahih)(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 ـ صلى الله عليه وسلم ـ " 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 .
