Question:
I wanted to know whether my uncle’s daughter is my mahram. He has two wifes. One of my uncle’s wife A (the elder) breastfed me. My uncle’s other wife B (the junior) has a daughter C. Is this daughter (C) from the wife B my mahram? from Hanafi POV?
Answer:
She is marriageable to you, and Allah knows best.
