Islam has made suckling a bond like blood relation, and it has established the unlawfulness of marriage by suckling like the unlawfulness of marriage due to blood relations. It has forbidden a man from marrying his sister, mother, maternal aunt, or paternal aunt by suckling, and so on. In this Hadīth, the Prophet (may Allah's peace and blessings be upon him) informs about the amount that does not establish the ruling on suckling that makes marriage unlawful. He says: "One suckling or two or one sucking or two does not make marriage unlawful." This was said in response to someone who asked about one suckling and two. So, he replied that they do not make marriage unlawful, whether this suckling happens before the completion of two years or beyond that. The amount that makes marriage unlawful is five sucklings taken before the completion of two years. In a Hadīth by Muslim, ‘Ā’ishah (may Allah be pleased with her) said: "In what was sent down in the Qur’an was ten known sucklings that make (marriage) unlawful. Afterwards, they were abrogated by five known ones. Then the Messenger of Allah (may Allah's peace and blessings be upon him) passed away while they were part of what was recited in the Qur’an." And ’Umm Salamah reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "The only suckling which makes marriage unlawful is what is taken from the breast and enters the bowels and is taken before the time of weaning."
