Al-Baqarah 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 ٱللَّهَ بِمَا تَعْمَلُونَ بَصِيرٌ

wa-in ṭallaqtumūhunna min qabli an tamassūhunna waqad faraḍtum lahunna farīḍatan faniṣ'fu mā faraḍtum illā an yaʿfūna aw yaʿfuwā alladhī biyadihi ʿuq'datu l-nikāḥi wa-an taʿfū aqrabu lilttaqwā walā tansawū l-faḍla baynakum inna l-laha bimā taʿmalūna baṣīrun

And if you divorce them before you have touched them and you have already specified for them an obligation, then [give] half of what you specified - unless they forego the right or the one in whose hand is the marriage contract foregoes it. And to forego it is nearer to righteousness. And do not forget graciousness between you. Indeed Allāh, of whatever you do, is Seeing.
