Yahya related to me from Malik from Yahya ibn Said that a man said to Abu Musa al-Ashari, "I drank some milk from my wife's breasts and it went into my stomach."

Abdullah ibn Masud said, "There is only kinship by suckling in the first two years." Abu Musa said, "Do not ask me about anything while this learned man is among you
