Yahya related to me from Malik from Ibn Shihab from Anas ibn Malik that the Messenger of Allah ﷺ was brought some milk which was mixed with well-water. There was a Bedouin at his right side and Abu Bakr as-Siddiq on his left. He drank and then gave it to the Bedouin and said, "The right-hand to the right-hand."
أَنَّ رَسُولَ اللَّهِ ﷺ أُتِيَ بِلَبَنٍ قَدْ شِيبَ بِمَاءٍ مِنَ الْبِئْرِ وَعَنْ يَمِينِهِ أَعْرَابِيٌّ وَعَنْ يَسَارِهِ أَبُو بَكْرٍ الصِّدِّيقُ فَشَرِبَ ثُمَّ أَعْطَى الأَعْرَابِيَّ وَقَالَ الأَيْمَنَ فَالأَيْمَنَ
