Sahih Muslim 2309aBook 43, Hadith 70
حَدَّثَنَا سَعِيدُ بْنُ مَنْصُورٍ، وَأَبُو الرَّبِيعِ، قَالاَ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ ثَابِتٍ الْبُنَانِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ خَدَمْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَشْرَ سِنِينَ وَاللَّهِ مَا قَالَ لِي أُفًّا . قَطُّ وَلاَ قَالَ لِي لِشَىْءٍ لِمَ فَعَلْتَ كَذَا وَهَلاَّ فَعَلْتَ كَذَا زَادَ أَبُو الرَّبِيعِ لَيْسَ مِمَّا يَصْنَعُهُ الْخَادِمُ . وَلَمْ يَذْكُرْ قَوْلَهُ وَاللَّهِ .
I served the Messenger of Allah (ﷺ) for ten years, and, by Allah, he never said to me any harsh word, and he never said to me about a thing as to why I had done that and as to why I had not done that. Abu Rabi' has made this addition (in this narration):" The work which a servant should do." There is no mention of his words" By Allah".
