Sura al-Baqara 2:237

وَإِن طَلَّقْتُمُوهُنَّ مِن قَبْلِ أَن تَمَسُّوهُنَّ وَقَدْ فَرَضْتُمْ لَهُنَّ فَرِيضَةً فَنِصْفُ مَا فَرَضْتُمْ إِلَّآ أَن يَعْفُونَ أَوْ يَعْفُوَا۟ ٱلَّذِى بِيَدِهِۦ عُقْدَةُ ٱلنِّكَاحِ وَأَن تَعْفُوٓا۟ أَقْرَبُ لِلتَّقْوَىٰ وَلَا تَنسَوُا۟ ٱلْفَضْلَ بَيْنَكُمْ إِنَّ ٱللَّـهَ بِمَا تَعْمَلُونَ بَصِيرٌ

And if ye divorce them before consummation, but after the fixation of a dower for them, then the half of the dower (Is due to them), unless they remit it or (the man's half) is remitted by him in whose hands is the marriage tie; and the remission (of the man's half) is the nearest to righteousness. And do not forget Liberality between yourselves. For Allah sees well all that ye do.
