Al-Baqarah 2:229

ٱلطَّلَٰقُ مَرَّتَانِۖ فَإِمۡسَاكُۢ بِمَعۡرُوفٍ أَوۡ تَسۡرِيحُۢ بِإِحۡسَٰنٖۗ وَلَا يَحِلُّ لَكُمۡ أَن تَأۡخُذُواْ مِمَّآ ءَاتَيۡتُمُوهُنَّ شَيۡـًٔا إِلَّآ أَن يَخَافَآ أَلَّا يُقِيمَا حُدُودَ ٱللَّهِۖ فَإِنۡ خِفۡتُمۡ أَلَّا يُقِيمَا حُدُودَ ٱللَّهِ فَلَا جُنَاحَ عَلَيۡهِمَا فِيمَا ٱفۡتَدَتۡ بِهِۦۗ تِلۡكَ حُدُودُ ٱللَّهِ فَلَا تَعۡتَدُوهَاۚ وَمَن يَتَعَدَّ حُدُودَ ٱللَّهِ فَأُوْلَـٰٓئِكَ هُمُ ٱلظَّـٰلِمُونَ 229

Divorce is twice. Then, either keep [her] in an acceptable manner or release [her] with good treatment. And it is not lawful for you to take anything of what you have given them unless both fear that they will not be able to keep [within] the limits of Allah. But if you fear that they will not keep [within] the limits of Allah, then there is no blame upon either of them concerning that by which she ransoms herself. These are the limits of Allah, so do not transgress them. And whoever transgresses the limits of Allah - it is those who are the wrongdoers
