Anas bin Malik said, that once a domestic sheep was milked for Allah's Messenger (ﷺ) while he was in thehouse of Anas bin Malik. The milk was mixed with water drawn from the well in Anas's house. Atumbler of it was presented to Allah's Messenger (ﷺ) who drank from it. Then Abu Bakr was sitting on hisleft side and a bedouin on his right side. When the Prophet (ﷺ) removed the tumbler from his mouth,`Umar was afraid that the Prophet (ﷺ) might give it to the bedouin, so he said. "O Allah's Messenger (ﷺ)! Give itto Abu Bakr who is sitting by your side." But the Prophet (ﷺ) gave it to the bedouin, who was to his rightand said, "You should start with the one on your right side."
