The brother of the maternal uncle through breastfeeding is not a mahram

Question:
From Jazan, a sister: (L. M. H.) asks and says: My mother’s maternal uncle’s brother through breastfeeding, is he a mahram to me, and may I uncover my face in front of him? Or is he not among the mahrams?

Answer:
No, he is not among the mahrams. The brother of the maternal uncle is not a mahram, unless he is a maternal uncle. If you have a maternal uncle, for example: Zayd is your mother’s brother through breastfeeding or through blood relation, then he is also a maternal uncle to you and a mahram to you. But his brother who is not a breastling of your mother, and is not a maternal uncle to you, is not a mahram; because he may have a foreign brother from his father, or a maternal uncle through breastfeeding, so he would not be a maternal uncle to you. Your maternal uncle is the one who has a breastfeeding relationship with your mother. If he was breastfed by her mother or her grandmother, he becomes a maternal uncle to her, and thus a maternal uncle to you through breastfeeding or through blood relation. As for his brother who is not a maternal uncle, he is not a maternal uncle to you, and he is not a mahram to you. Yes.
