The Messenger of Allah ﷺ said, "A woman is not to be married to a man who is already married to her paternal aunt, nor to one already married to her maternal aunt, nor is a woman to be married to a man already married to her brother's daughter, nor to one already married to her sister's daughter."
حدثنا يونس حدثنا حماد يعني ابن زيد عن عاصم عن الشعبي
قال رسول الله ﷺ لا تنكح المرأة على عمتها ولا على خالتها ولا المرأة على ابنة أخيها ولا على ابنة أختها
