Ruling on the marriage of the brothers of a breastfed child to the daughters of the woman who breastfed their brother

Regarding this message we received from the listener (A. A. M.) from Iraq, he says: We are five brothers, and my aunt breastfed my eldest brother, while my mother did not breastfeed any of her children, and I am the youngest of my brothers. Is it permissible for me to marry my aunt’s daughter? Please guide us?
Answer: Yes, there is no harm. It is only her daughters who are forbidden to the one who was breastfed by her. As for the brothers who were not breastfed, it is not forbidden for them to marry the aunt’s daughters, because breastfeeding is specific to the one who was breastfed only. If the aunt’s daughters did not breastfeed from your mother, O questioner! Nor from your sisters, nor from your father’s wife, meaning: they did not breastfeed from a woman whose daughter is forbidden to you, then there is no harm on you. And the fact that your eldest brother was breastfed by your aunt does not prevent the rest from marrying the aunt’s daughters. Yes.
