Ruling on a woman marrying the brother of a husband from whom she was breastfed

Question:
A girl was breastfed by her father's sister. Is she permissible to marry her husband's brothers, meaning the brothers of the breastfeeding wife?

Answer:
If a woman is breastfed by another woman with a complete breastfeeding, five times or more, then the one who provided the milk, who is the husband, becomes her father, and the breastfeeding woman becomes her mother. The husband's brothers become her paternal uncles, and his sisters become her paternal aunts. The woman's brothers become her maternal uncles, and her sisters become her maternal aunts. It is not permissible for them to marry her if the breastfeeding is lawful, meaning five times or more within the two-year period.
