The Prophet ﷺ said, "None of you should propose marriage to a woman already proposed to by his brother, nor bargain over a purchase already being negotiated by his brother. A woman should not be married while her paternal aunt or her maternal aunt is also married to the same man. A woman should not request the divorce of her sister so as to empty her dish for herself. Let her marry, for she will only receive what Allah has decreed for her."
حدثنا محمد بن جعفر قال حدثنا هشام القردوسي عن محمد
عن النبي ﷺ أنه قال لا يخطب أحدكم على خطبة أخيه ولا يستام على سوم أخيه ولا تنكح المرأة على عمتها ولا على خالتها ولا تسأل طلاق أختها لتكتفئ صحفتها ولتنكح فإنما لها ما كتب الله لها
