The Prohibition of a Woman for a Man Who Raised Her as a Child

Question:
Among the questions of this questioner from Syria, he says: A young boy’s mother passed away, and a woman raised him in her house with her children without breastfeeding. Does this woman and her daughters become mahram (forbidden relatives) to him?

Answer:
Raising a child does not make her a nursing mother. If a woman raises a young boy and does not breastfeed him, he does not become her son, nor does he become a brother to her children. Rather, he is a non-mahram (foreigner) with whom she and her daughters cannot be in seclusion, except through breastfeeding. If she breastfed him five times within the first two years, she would become his mother. However, mere upbringing, even if she treated him well and raised him, does not make her his mother, nor do her daughters become his sisters. Rather, he is a non-mahram to all of them. Yes.
