Narrated Anas bin Malik: "The Messenger of Allah was brought some milk which was mixed with some water. On his right was a Bedouin and on his left was Abu Bakr. So he drank, then he gave it to the Bedouin and said: 'The right, then the right.'" He said: There are narrations on this topic from Ibn 'Abbas, Sahl bin Sa'd, Ibn 'Umar, and 'Abdullah bin Busr. [Abu 'Eisa said:] This Hadith is Hasan Sahih.

حَدَّثَنَا الأَنْصَارِيُّ، حَدَّثَنَا مَعْنٌ، حَدَّثَنَا مَالِكٌ، قَالَ وَحَدَّثَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم أُتِيَ بِلَبَنٍ قَدْ شِيبَ بِمَاءٍ وَعَنْ يَمِينِهِ أَعْرَابِيٌّ وَعَنْ يَسَارِهِ أَبُو بَكْرٍ فَشَرِبَ ثُمَّ أَعْطَى الأَعْرَابِيَّ وَقَالَ ‏ "‏ الأَيْمَنَ فَالأَيْمَنَ ‏" ‏ ‏.‏ قَالَ وَفِي الْبَابِ عَنِ ابْنِ عَبَّاسٍ وَسَهْلِ بْنِ سَعْدٍ وَابْنِ عُمَرَ وَعَبْدِ اللَّهِ بْنِ بُسْرٍ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
