Al Baqarah Ayah 229

ٱلطَّلَـٰقُ مَرَّتَانِ‌ۖ فَإِمْسَاكُۢ بِمَعْرُوفٍ أَوْ تَسْرِيحُۢ بِإِحْسَـٰنٍ‌ۗ وَلَا يَحِلُّ لَكُمْ أَن تَأْخُذُواْ مِمَّآ ءَاتَيْتُمُوهُنَّ شَيْــًٔا إِلَّآ أَن يَخَافَآ أَلَّا يُقِيمَا حُدُودَ ٱللَّهِ‌ۖ فَإِنْ خِفْتُمْ أَلَّا يُقِيمَا حُدُودَ ٱللَّهِ فَلَا جُنَاحَ عَلَيْهِمَا فِيمَا ٱفْتَدَتْ بِهِۦ‌ۗ تِلْكَ حُدُودُ ٱللَّهِ فَلَا تَعْتَدُوهَا‌ۚ وَمَن يَتَعَدَّ حُدُودَ ٱللَّهِ فَأُوْلَـٰٓئِكَ هُمُ ٱلظَّـٰلِمُونَ ٢٢٩ Divorce may be retracted twice, then the husband must retain ?his wife? with honour or separate ?from her? with grace. It is not lawful for husbands to take back anything of the dowry given to their wives, unless the couple fears not being able to keep within the limits of Allah. So if you fear they will not be able to keep within the limits of Allah, there is no blame if the wife compensates the husband to obtain divorce. These are the limits set by Allah, so do not transgress them. And whoever transgresses the limits of Allah, they are the ?true? wrongdoers.
