Messenger of Allah ﷺ 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."
قَالَ رَسُولُ اللَّهِ ﷺ لاَ تَسْأَلِ الْمَرْأَةُ طَلاَقَ أُخْتِهَا لِتَسْتَفْرِغَ صَحْفَتَهَا وَلْتَنْكِحْ فَإِنَّ لَهَا مَا قُدِّرَ لَهَا
