Question:
If a man has a sister through breastfeeding, do her older and younger sisters become his sisters, and vice versa?

Answer:
Yes, if a person is breastfed by a woman five known times within the first two years, he becomes her son and becomes a brother to all her children, whether they are older than him or younger than him. Everyone this woman gave birth to, since she is the woman who breastfed him, are his brothers, whether they are older than him, younger than him, or the same age as him, and whether they are from one husband or from several husbands; they are all his brothers. As for his own brothers, they do not become related to him through this woman, and they have no connection to this breastfeeding, because breastfeeding does not extend to the relatives of the breastfed child, but only to the breastfed child himself and his descendants, namely his children and the children of his children, and so on. Yes. May Allah reward you with good, and may He do you well.
