Anas b. Malik said:

The Prophet ﷺ was brought milk that was mixed with water. A nomad Arab was on his right and Abu Bakr was on his left. He himself drank and gave it to the nomad Arab, and said: He who is on the right , then he who is on his right then he who is on his right.

حَدَّثَنَا الْقَعْنَبِيُّ عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ النَّبِيَّ ﷺ أُتِيَ بِلَبَنٍ قَدْ شِيبَ بِمَاءٍ وَعَنْ يَمِينِهِ أَعْرَابِيٌّ وَعَنْ يَسَارِهِ أَبُو بَكْرٍ فَشَرِبَ ثُمَّ أَعْطَى الأَعْرَابِيَّ وَقَالَ
" الأَيْمَنَ فَالأَيْمَنَ " .
