The Messenger of Allah ﷺ forbade that a woman be married to a man who is already married to her Amtah or maternal aunt.
أخبرني محمد بن آدم عن ابن المبارك عن عاصم عن الشعبي قال سمعت
نهى رسول الله ﷺ أن تنكح المرأة على عمتها وخالتها
Bukhari narrated it, no. 5108 (see the preceding hadith no. 3298), from the hadith of Ibn Mubarak, by this route.
