وَإِن طَلَّقتُموهُنَّ مِن قَبلِ أَن تَمَسّوهُنَّ وَقَد فَرَضتُم لَهُنَّ فَريضَةً فَنِصفُ ما فَرَضتُم إِلّا أَن يَعفونَ أَو يَعفُوَ الَّذي بِيَدِهِ عُقدَةُ النِّكاحِ ۚ وَأَن تَعفوا أَقرَبُ لِلتَّقوىٰ ۚ وَلا تَنسَوُا الفَضلَ بَينَكُم ۚ إِنَّ اللَّهَ بِما تَعمَلونَ بَصيرٌ

And to forego it is nearer to righteousness. And do not forget graciousness between you. Indeed Allah, of whatever you do, is Seeing.
