Question:
This questioner, S.A. from Jazan, says: A girl was breastfed with me more than five times. Is this girl a mahram to me and my brothers?
Answer:
Without a doubt, if she was breastfed by a woman along with you more than five times, or five times—this is the dividing line; if it is more than that, and this occurred within the two-year period, then this establishes the prohibition of marriage. She becomes your foster sister and a mahram to you. Allah the Exalted said, "And your sisters," when He mentioned the prohibited women.[An-Nisa 4:23] Yes.
