Ruling on a man who proposed to a woman from whom he was breastfed by her grandmother

Question:
A listener says: Al-Tayyib al-Bashir Muhammad Ali says: I proposed to a girl, but three days after the proposal, my mother told me that I had been breastfed by the girl's uncle, who is younger than her father, meaning: by her mother—as he says in his question—and the girl's father has learned of this news. Now, her mother has also said that she breastfed me. Can I marry this girl?

Answer:
If you were breastfed by the girl's paternal grandmother a complete breastfeeding, five times or more, and you were within the two-year period; then you are her uncle, the brother of her father, so you cannot marry her. If you were breastfed by her paternal grandmother five times or more, even in one sitting, and you were within the two-year period before weaning; then you are her uncle at that time, and she is not permissible for you. Yes.

The presenter : May Allah reward you with good, and may He do you good.
