Is it permissible for the son of a man, who was suckled by his father’s wife, to marry the sister of that man, if the suckling occurred before the father’s marriage to the girl’s mother?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
It is not permissible for a man to marry his paternal sister if he was nursed by his father's wife with her milk, because by doing so, he becomes a brother to her and to all his father's children through suckling, based on the Almighty's saying: "And your sisters through suckling," and the Prophet's (peace be upon him) saying: "Suckling prohibits what lineage prohibits."
