Hazrat Abdullah bin Mas'ud (may Allah be pleased with him) narrates that I was a young boy and used to herd the goats of Uqbah bin Abi Mu'it. The Prophet صلی اللہ علیہ وسلم and Hazrat Abu Bakr came while they were fleeing from the polytheists, and said, "O boy! Do you have any milk for us to drink?" I said, "I am entrusted (with these goats), and I cannot give you (milk)." The Prophet صلی اللہ علیہ وسلم said, "Do you have a goat that is six months old and upon which no male has mounted?" I said, "Yes!" I brought it to them. The Prophet صلی اللہ علیہ وسلم untied its legs, touched its udders, and prayed. Then Hazrat Abu Bakr brought a hollowed-out stone to you, and you milked the goat into it. You drank the milk, and Hazrat Abu Bakr also drank, then I drank. Then you said to the udder, "Shrink," so it shrank. After that, I came to you and requested, "Teach me some of these things." You said, "You are a learned boy."
