Sahih Muslim Book - 36, Hadith - 5290

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، وَعَمْرٌو النَّاقِدُ ، وَزُهَيْرُ بْنُ حَرْبٍ ، وَمُحَمَّدُ بْنُ عَبْدِ اللهِ بْنِ نُمَيْرٍ ، وَاللَّفْظُ لِزُهَيْرٍ ، قَالُوا : حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ ، عَنِ الزُّهْرِيِّ ، عَنْ أَنَسٍ ، قَالَ : قَدِمَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْمَدِينَةَ وَأَنَا ابْنُ عَشْرٍ ، وَمَاتَ وَأَنَا ابْنُ عِشْرِينَ ، وَكُنَّ أُمَّهَاتِي يَحْثُثْنَنِي عَلَى خِدْمَتِهِ ، فَدَخَلَ عَلَيْنَا دَارَنَا فَحَلَبْنَا لَهُ مِنْ شَاةٍ دَاجِنٍ ، وَشِيبَ لَهُ مِنْ بِئْرٍ فِي الدَّارِ ، فَشَرِبَ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَقَالَ لَهُ عُمَرُ ، وَأَبُو بَكْرٍ عَنْ شِمَالِهِ: يَا رَسُولَ اللهِ ، أَعْطِ أَبَا بَكْرٍ ، فَأَعْطَاهُ أَعْرَابِيًّا عَنْ يَمِينِهِ ، وَقَالَ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: الأَيْمَنَ فَالأَيْمَنَ.

It was narrated that Anas said: "The Prophet (s.a.w) came to Al-Madinah when I was ten years old, and he died when I was twenty years old. My mothers (i.e., my mother and my maternal aunts) used to urge me to serve him. He (s.a.w) entered upon us in our house and we milked a domestic sheep for him, and mixed it with water from a well in the house. The Messenger of Allah (s.a.w) drank, then 'Umar said to him - as Abu Bakr was sitting to his left - 'O Messenger of Allah, give it to Abu Bakr.' But he gave it to a Bedouin who was on his right, and the Messenger of Allah (s.a.w) said: 'To the (immediate) right then the next to the right."'
