Surat Al-Baqara (The Cow) - البقرة

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 ﴿٢٣٧﴾

And if you divorce them before you have touched them and you have appointed for them a portion, then (pay to them) half of what you have appointed, unless they relinquish or he should relinquish in whose hand is the marriage tie; and it is nearer to righteousness that you should relinquish; and do not neglect the giving of free gifts between you; surely Allah sees what you do.
