The Messenger of Allah ﷺ forbade that a woman be married to a man who is already married to her Amtah or her maternal aunt.
حدثنا عبدة بن سليمان حدثنا عاصم يعني الأحول عن عامر
نهى رسول الله ﷺ أن تزوج المرأة على عمتها أو على خالتها
Its isnad is sahih, and Amir is Shaybi. The hadith previously appeared at 9099.
