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".
خَدَمْتُ رَسُولَ اللَّهِ ﷺ 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
