I served the Messenger of Allah ﷺ for ten years, and by Allah, he never scolded me or said to me "uff" (an expression of annoyance) and he never asked me why I did something or why I did not do something except that he said to me, "Why did you do it?" or "Why did you not do it?"
خَدَمْتُ رَسُولَ اللهِ ﷺ عَشْرَ سِنِينَ لَا وَاللهِ مَاسَبَّنِي سَبَّةً قَطُّ وَلَا قَالَ لِي أُفٍّ قَطُّ وَلَا قَالَ لِشَيْءٍ فَعَلْتُهُ لِمَ فَعَلْتَهُ وَلَا لِشَيْءٍ لَمْ أَفْعَلْهُ أَلَّا فَعَلْتَهُ
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
"خَدَمْتُ رَسُولَ الله ﷺ عَشْرَ سنِينَ، لاَ والله مَا سَبَّنِى سَبَّةً قَطُّ، وَلاَ قَالَ لِى أُفٍّ قَطُّ، وَلاَ قَالَ لِى لِشَئ فَعَلتُهُ (لمَ فَعَلتَهُ) (*) وَلا لشئٍ لَمْ أَفْعَلهُ: أَلاَ فَعَلتَهُ! ".
