The ruling on a man marrying his sister’s sister through breastfeeding

Question:
He also appended a question to the message, asking: Is it permissible for me to marry my paternal cousin, who is younger than the one my mother breastfed along with my sister? I should mention that there was no breastfeeding between my brothers and this second paternal cousin. If it is permissible for me to marry her, please clarify this; and if it is not permissible, please clarify that as well. May Allah reward you with good?

Answer:
There is nothing wrong with your paternal cousin who was not breastfed by your mother; it is permissible for you, or any of your brothers, to marry her, provided that you were not breastfed by her mother and she was not breastfed by your mother. Breastfeeding kinship applies specifically to the one who was breastfed by your mother. As for her sisters who were not breastfed by your mother, they are lawful for you, because they are paternal cousins who are lawful, provided that you were not breastfed by their mother. Therefore, there is no blame on you for marrying her. The only one who is forbidden to you is the one who was specifically breastfed by your mother. Yes.
