The ruling on marrying the daughter of the sister of the wife of one’s father

Question:
This questioner asks about breastfeeding. He was breastfed by the wife of his maternal uncle, Nur al-Din. Is it permissible for him to marry his maternal uncle’s daughter from a second wife? It is known that the aforementioned maternal uncle’s daughter is Nur al-Din’s sister from their father. I ask for guidance on this. May Allah preserve you.

Answer:
Yes, if you were breastfed by the wife of a man, whether he is your maternal uncle or not, and if you were breastfed by the wife of a man with a complete breastfeeding of five feedings within the two-year period, then this man becomes your father through breastfeeding, and his children, both daughters and sons, all of them become your siblings through breastfeeding from all his wives, from the wife who breastfed you and from his other wives; all their children are your siblings through breastfeeding. Yes. And the two sheep are your uncle, O Farah. Yes.
His sister from his father becomes his aunt. A sister from his father becomes an aunt through breastfeeding, if he was breastfed by her mother. It is possible that she becomes his sister by blood and his aunt through breastfeeding. Yes.
