Yahya related to me from Malik from Abdullah ibn Dinar from Sulayman ibn Yasar and from Urwa ibn az-Zubayr from A'isha umm al- muminin, that the Messenger of Allah, may Allah bless him and grant him peace, said, " What is haram by birth is haram by suckling."
Muwatta Malik Book 30, Hadith 16
← Previous Hadith 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." Abu Musa said, "I can only but think that she is haram for you." Abdullah ibn Masud said, "Look at what opinion you are giving the man." Abu Musa said, "Then what do you say?" 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."

Muwatta Malik Book 30, Hadith 15 Next Hadith → Yahya related to me from Malik that Muhammad ibn Abd ar-Rahman ibn Nawfal said, ''Urwa ibn az-Zubayr informed me from A'isha umm al- muminin that Judama bint Wahb al-Asadiyya informed her that she heard the Messenger of Allah, may Allah bless him and grant him peace, say, 'I intended to prohibit ghila but I remembered that the Greeks and Persians do that without it causing any injury to their children.' "

Malik explained, "Ghila is that a man has intercourse with his wife while she is suckling."
