Anas bin Malik (RA) reported: Allahs Messenger ﷺ came to our house and he asked for a drink. We milked a goat for him and then mixed it (the milk) with the water of this well of mine. I gave it to Allahs Messenger ﷺ and he drank it, while Abu Bakr (RA) was on his left and Umar was in front of him, and a desert Arab was on his right. When Allahs Messenger ﷺ had finished the drink, Umar said: Allahs Messenger, here is Abu Bakr, give him to drink; but Allahs Messenger ﷺ gave it to the desert Arab and he left out Abu Bakr (RA) and Umar. And Allahs Messenger ﷺ said: Those on the right, those on the right, those on the right (deserve preference). Anas said: This is the Sunnah, this is the Sunnah, this is the Sunnah.
