What is the ruling on a brother marrying his brother's sister through رضاعة (milk-kinship) if she was born after the رضاعة (milk-feeding) occurred?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
"Breastfeeding establishes what is prohibited by lineage, so the suckling child becomes a son to the wet nurse and to her husband, the owner of the milk. This prohibition applies only to the suckling child, not to his siblings. Based on this, it is permissible for the two young men who were suckled by two different women to marry each other's sister, unless other suckling is proven between them."
