Breastfeeding of the fiancée’s sister by the husband’s sister does not make her forbidden

Question: I am a young man, 21 years old, and I have decided to marry one of the girls. After the proposal, it became clear to me that my older sister had breastfed me, and had also breastfed the older brother and sister of my fiancée. So, should I marry that girl?

Answer: If the situation is as described in the question, there is no blame on you in marrying the woman mentioned; because your sister’s breastfeeding of her brother and sister does not make her forbidden to you. And success is from Allah.
