Musannaf Ibn Abi Shaybah

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 ﷺ 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 ﷺ 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 ﷺ 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."
