Sahih Bukhari · Hadith 6681

حدثنا عبد الله بن يوسف، أخبرنا مالك، عن أبي الزناد، عن الأعرج، عن أبي هريرة، قال قال رسول الله صلى الله عليه وسلم ‏"‏ لا تسأل المرأة طلاق أختها لتستفرغ صحفتها، ولتنكح، فإن لها ما قدر لها ‏"‏‏.‏

Narrated Abu Huraira: Allah's Apostle said, "No woman should ask for the divorce of her sister (Muslim) so as to take her place, but she should marry the man (without compelling him to divorce his other wife), for she will have nothing but what Allah has written for her."
