وَإِن طَلَّقْتُمُوهُنَّ مِن قَبْلِ أَن تَمَسُّوهُنَّ وَقَدْ فَرَضْتُمْ لَهُنَّ فَرِيضَةًۭ فَنِصْفُ مَا فَرَضْتُمْ إِلَّآ أَن يَعْفُونَ أَوْ يَعْفُوَا۟ ٱلَّذِى بِيَدِهِۦ عُقْدَةُ ٱلنِّكَاحِ ۚ وَأَن تَعْفُوٓا۟ أَقْرَبُ لِلتَّقْوَىٰ ۚ وَلَا تَنسَوُا۟ ٱلْفَضْلَ بَيْنَكُمْ ۚ إِنَّ ٱللَّهَ بِمَا تَعْمَلُونَ بَصِيرٌ
If ye divorce them before ye have touched them and ye have appointed unto them a portion, then (pay the) half of that which ye appointed, unless they (the women) agree to forgo it, or he agreeth to forgo it in whose hand is the marriage tie. To forgo is nearer to piety. And forget not kindness among yourselves. Allah is Seer of what ye do.
Surah Al-Baqara(2:237)
Sahih al-Bukhari
Sales and Trade
Chapter: Not to cancel a bargain already agreed upon
Narrated Abu Huraira:
Allah's Messenger (ﷺ) forbade the selling of things by a town dweller on behalf of a desert dweller; and similarly Najsh was forbidden. And one should not urge somebody to return the goods to the seller so as to sell him his own goods; nor should one demand the hand of a girl who has already been engaged to someone else; and a woman should not try to cause some other woman to be divorced in order to take her place.
Sahih al-Bukhari 2140
