Al-Adab Al-Mufrad 164
Anas said, "The Prophet ﷺ came to Madina without any servant. Abu Talha took my hand and brought me to the Prophet ﷺ and said, 'Prophet of Allah!' This is Anas, a clever and intelligent boy. Let him serve him.'" Anas said, "I served him when he was at home and on journeys from the time he came to Madina until he died, may Allah bless him and grant him peace. He never said to me about anything I had done, 'Why did you do this?' nor did he say to me about something I had not done, 'Why did you not do such-and-such?'"
حَدَّثَنَا أَبُو مَعْمَرٍ، قَالَ: حَدَّثَنَا عَبْدُ الْوَارِثِ، قَالَ: حَدَّثَنَا عَبْدُ الْعَزِيزِ، عَنْ أَنَسٍ قَالَ: قَدِمَ النَّبِيُّ ﷺ الْمَدِينَةَ وَلَيْسَ لَهُ خَادِمٌ، فَأَخَذَ أَبُو طَلْحَةَ بِيَدِي، فَانْطَلَقَ بِي حَتَّى أَدْخَلَنِي عَلَى النَّبِيِّ ﷺ، فَقَالَ: يَا نَبِيَّ اللهِ، إِنَّ أَنَسًا غُلاَمٌ كَيِّسٌ لَبِيبٌ، فَلْيَخْدُمْكَ. قَالَ: فَخَدَمْتُهُ فِي السَّفَرِ وَالْحَضَرِ، مَقْدَمَهُ الْمَدِينَةَ حَتَّى تُوُفِّيَ ﷺ، مَا قَالَ لِي لِشَيْءٍ صَنَعْتُ: لِمَ صَنَعْتَ هَذَا هَكَذَا؟ وَلاَ قَالَ لِي لِشَيْءٍ لَمْ أَصْنَعْهُ: أَلاَ صَنَعْتَ هَذَا هَكَذَا؟.
