Will the maternal uncle become a father through breastfeeding if his wife breastfeeds an infant? And will the infant's wife be prohibited to her maternal uncle? And is it permissible for her to remove her hijab in front of him? And are the maternal uncle's wife's sisters prohibited to the infant?

If your maternal uncle's wife breastfed you five times, she becomes your mother through nursing (rada'a), and your maternal uncle becomes your father through nursing. Your wife is forbidden to your maternal uncle because she is the wife of his son through nursing. It is permissible for her to remove her hijab in front of him and for him to see from her what is permissible for maharim (unmarriageable kin). The sisters of your nursing maternal uncle's wife are your maternal aunts through nursing and are maharim to you.
