Umm Sulaym took me by the hand and brought me to the Prophet's ﷺ presence in Madinah. She said, "O Messenger of Allah, this is my son and he is a young scribe." He said, "So, I served him for nine years and he never said to me about anything I did that it was bad, or poorly done."
أَخَذَتْ أُمُّ سُلَيْمٍ بِيَدِي مَقْدَمَ النَّبِيِّ ﷺ الْمَدِينَةَ فَأَتَتْ بِي رَسُولَ اللهِ ﷺ فَقَالَتْ يَا رَسُولَ اللهِ هَذَا ابْنِي وَهُوَ غُلَامٌ كَاتِبٌ قَالَ فَخَدَمْتُهُ تِسْعَ سِنِينَ فَمَا قَالَ لِي لِشَيْءٍ قَطُّ صَنَعْتُهُ أَسَأْتَ أَوْ بِئْسَ مَا صَنَعْتَ
