Umm al-Fadl stated that God’s Prophet said, “Being suckled once or twice does not make marriage unlawful.” In ‘A’isha’s version he said, “One or two sucks do not make marriage unlawful.” In another by Umm al-Fadl he said, “One suckling or two does not make marriage unlawful.”
‘Ali said, “Messenger of God, would you like the daughter of your paternal uncle Hamza, for she is the most beautiful girl in Quraish?” He replied, “Do you not know that Hamza is my foster-brother, and that God has prohibited by reason of fosterage what He has prohibited by reason of genealogy?”
‘A’isha said that in what was sent down in the Qur’an ten known sucklings made marriage unlawful, but they were abrogated by five known ones, and when God’s Messenger died these words were among what was recited in the Qur’an.
My paternal uncle through fosterage came and asked permission to enter, but I refused to allow him till I asked God’s Messenger. When he came I asked him and he said, “He is your paternal uncle, so give him permission.” I replied, “Messenger of God, it was only the woman who suckled me and not the man” whereupon he said, “He is your paternal uncle, so let him come in where you are.” That was after seclusion was instituted for us.
