Sahih al-Bukhari 5619

Ismāʿīl narrated to us; he said: Mālik narrated to me, from Ibn Shihāb, from Anas ibn Mālik (may Allah be pleased with him): The Messenger of Allah ﷺ was brought milk diluted with water. A Bedouin was on his right and Abū Bakr on his left. He drank, then gave it to the Bedouin and said, “The one on the right, the one on the right.”
