Narrated Anas ibn Malik:

I served the Prophet ﷺ at Medina for ten years. I was a boy. Every work that I did was not according to the desire of my master, but he never said to me: Fie, nor did he say to me: Why did you do this? or Why did you not do this?

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، حَدَّثَنَا سُلَيْمَانُ، - يَعْنِي ابْنَ الْمُغِيرَةِ - عَنْ ثَابِتٍ، عَنْ أَنَسٍ، قَالَ خَدَمْتُ النَّبِيَّ ﷺ عَشْرَ سِنِينَ بِالْمَدِينَةِ وَأَنَا غُلاَمٌ لَيْسَ كُلُّ أَمْرِي كَمَا يَشْتَهِي صَاحِبِي أَنْ أَكُونَ عَلَيْهِ مَا قَالَ لِي فِيهَا أُفٍّ قَطُّ وَمَا قَالَ لِي لِمَ فَعَلْتَ هَذَا أَوْ أَلاَ فَعَلْتَ هَذَا .
