Ruling on the daughters of a wet nurse being uncovered before her brother’s sons

Question:
This sister says that in her question she stated: I nursed my brother, and I was forty years old, for a full month, knowing that he only nursed at night and at Fajr. I have been blessed with sons, and so has my brother. My question to the Shaykh: Are my daughters uncovered before his sons, and are his daughters uncovered before my sons? And may Allah reward you with good.

Answer:
Yes, if you nursed your brother with complete nursing, and you say that you nursed him for a full month, then he becomes your son. He is your brother by blood and your son by nursing. Your daughters become mahram (forbidden to marry) to your sons, because your sons become, rather, maternal uncles to her daughters by nursing. Your sons become maternal uncles to her daughters by nursing, and a maternal uncle is a mahram. The Messenger (peace and blessings be upon him) said: ease. Likewise, your daughters are mahram to his children because they are his aunts by nursing. Yes.
