Is a woman who was breastfed by her mother considered the daughter of her husband?

Question:
The listener, Salah ibn Ibrahim Mahmoud, residing in al-Qassim, sent a question saying: My mother gave birth to me while she was in the marriage bond with my father. Then my father divorced her after my birth, and another man married my mother. I had not yet reached weaning at that time, so I was breastfed by my mother after her last marriage more than five times, with full and satisfying feedings. Does this make me the son of my mother’s husband through breastfeeding and a brother to his children?

Answer:
You do not become his son. You are the son of his wife, his stepson. However, if your mother became pregnant, her milk dried up, and she gave birth to a boy or a girl, and she produced milk while you were still within the breastfeeding period and had not been weaned, you would become his son. If she breastfed you with her new milk, if she became pregnant while you were young, then gave birth, and milk came for the last child, and she breastfed you, and you had not reached weaning, then you would become his son through breastfeeding.
As for the fact that you were breastfed by her from the milk of the first husband, the milk of your father, after she married, this does not make you his son; because the milk is the milk of your father, which remained. But if she became pregnant by the new husband, and milk came after she delivered the pregnancy, and you were still within the two years, then she breastfed you from the milk of the new husband along with your new brother, you would become his son through breastfeeding. Yes.
