What is the ruling for one who learns that he married his sister through breastfeeding

Question:
Our brother says: I married my cousin's daughter, and she bore me two children. After several years of marriage, I learned that my wife had been breastfed by a woman who is a stranger to me, and I was also breastfed by her. This woman who breastfed both me and my wife is a stranger to us and has no relation to us. It is known that the breastfeeding did not occur within the same two-year period, but rather in two different periods. What is the ruling in this case? May Allah reward you with good.

Answer:
Allah, the Most Merciful, the Bestower of Mercy. Praise be to Allah, Lord of the worlds, and may Allah send prayers and blessings upon our Prophet Muhammad, and upon his family and all his Companions. To proceed: If it is established that you and your wife were breastfed by the same woman, and each of you was breastfed five times within the two-year period, then you are siblings through breastfeeding. Based on this, she is not lawful for you.
The saying of the Prophet (peace and blessings be upon him) , and his saying (peace and blessings be upon him) that breastfeeding prohibits what birth prohibits. This is mentioned in the saying of Allah the Exalted, when He mentioned the prohibited relatives, He said: . However, establishing this and examining it requires the judge's review. Refer to the Shari'ah court to look into the establishment of the breastfeeding and the verification of its conditions. Then the judge will rule according to what he sees as in accordance with the prescribed method, if Allah wills. Yes.
