Anas reported:
The Apostle of Allah (may peace he upon him) came to Medina when I was ten years old and he died when I was twenty years old. My mother exhorted me to serve him. He (the Holy Prophet) came to our house, and we ruined a flabby goat for him and mixed it (the milk) with water from the well of the house. Allah's Messenger ( صلی اللہ علیہ وسلم ) drank that. Umar and Abu Bakr on his left side said to him: Allah's Messenger, give it to Abu Bakr, but he (the Holy Prophet) gave it to the desert Arab who was on his right. Allah's Messenger ( صلی اللہ علیہ وسلم ) said: He who is on the right, then he who is on the right.
