Musnad Abi Ya'la 4985 — he said: I was a young boy grazing the goats

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he said: "I was a young boy grazing the goats of Uqbah bin Abi Mu'ayt when the Messenger of Allah (peace and blessings be upon him) and Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) came to me, and he (peace and blessings be upon him) asked: 'O boy, do you have any milk?' I said: 'Yes, but I am (their) trustee.' He (peace and blessings be upon him) said: 'Bring me a goat that no male has yet mounted.' I brought him (peace and blessings be upon him) a young kid or a yearling goat. The Messenger of Allah (peace and blessings be upon him) held it, then began to stroke its udder and supplicate until the udder let down milk. Then Sayyiduna Abu Bakr (may Allah be pleased with him) brought a (bowl-like) stone, into which he (peace and blessings be upon him) milked it. Then he (peace and blessings be upon him) said to Sayyiduna Abu Bakr (may Allah be pleased with him): 'Drink.' So Sayyiduna Abu Bakr (may Allah be pleased with him) drank, and after him the Prophet (peace and blessings be upon him) drank. Then he (peace and blessings be upon him) commanded the udder: 'Shrink back,' and it shrank and became as it had been before." Ibn Mas'ud (may Allah be pleased with him) said: "After this incident I came to the Prophet (peace and blessings be upon him) and said: 'O Messenger of Allah, teach me some of this speech, that is, of this Qur'an.' He (peace and blessings be upon him) passed his hand affectionately over my head and said: 'Indeed, you are a boy who is taught (and gifted).'" Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said: "So I learned seventy surahs directly from his (peace and blessings be upon him) blessed mouth, concerning which (their soundness and recitation) no human being can dispute with me."
