Is the wife's sister forbidden to the husband temporarily until the wife's death or divorce, and does the same ruling apply to the brother and his brother's wife?
Source: FtawySummarized from the full answer at Ftawy · imported Sep 2, 2026
Allah has forbidden combining two sisters in marriage, or a woman with her paternal aunt, or her maternal aunt, or her brother's daughter, or her sister's daughter; out of a concern for maintaining kinship ties. Therefore, it is not permissible for a man to marry his wife's sister or any other temporarily forbidden woman, except after her death or an irrevocable divorce. As for a brother's wife, she is not permissible for his brother except after her husband's death or an irrevocable divorce and the completion of her iddah (waiting period).
