Is it permissible to marry the daughter of one's brother through rada'a (nursing)?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
It is not permissible to marry one's niece through fosterage (رضاعة), based on the Prophet Muhammad's (peace be upon him) saying regarding Hamza's daughter: "She is not permissible for me. She is the daughter of my brother through fosterage," and his saying: "Fosterage prohibits what birth prohibits," and "Fosterage prohibits what lineage prohibits." And a niece by lineage is prohibited according to the Almighty's saying: (Forbidden to you are your mothers... and your brothers' daughters...).
