Sunan Ibn Majah Book 30, Hadith 3425

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ، عَنِ الزُّهْرِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ أُتِيَ بِلَبَنٍ قَدْ شِيبَ بِمَاءٍ وَعَنْ يَمِينِهِ أَعْرَابِيٌّ وَعَنْ يَسَارِهِ أَبُو بَكْرٍ فَشَرِبَ ثُمَّ أَعْطَى الأَعْرَابِيَّ وَقَالَ ‏ "‏ الأَيْمَنُ فَالأَيْمَنُ ‏"‏ ‏.‏

It was narrated from Anas bin Malik that the Messenger of Allah (ﷺ) was brought some milk mixed with water. On his right there was a Bedouin and on his left was Abu Bakr. He drank some, then he gave it to the Bedouin and said:“Pass it around to the right.”
