A man marrying a woman after his son by breastfeeding has divorced her

Q 2: A man married a divorced woman whose ex-husband suckled from the wife of this man who she is now married to. What is the ruling on this marriage? Does it make a difference if her ex-husband is his son by suckling? Please advise. May Allah reward you. A: The man having a wife who breastfed another person five times or more during his first two years after birth is not permitted to marry the ex-wife of the breastfed person, because she is considered the wife of his milk-son. A man is not permitted to marry the ex-wife of his biological son, because Allah (Exalted be He) clearly stated what women are not lawful to marry in His statement: ...the wives of your sons Similarly, a man is not permitted to marry the ex-wife of his milk son, because the Prophet (may blessings and peace of Allah be upon him) stated: Milk relationships are equal to blood relationships in rendering marriage unlawful, i.e. whatever is prohibited due to blood relationships is also prohibited by milk relationships. However, if the number of breastfeeding is less than five times or is doubted, it is not prohibited for him to marry as there is no definite impediment. (Part No. 21; Page No. 97
