The divorce is twice, after that, either you retain her on reasonable terms or release her with kindness. And it is not lawful for you (men) to take back (from your wives) any of your Mahr (bridal money given by the husband to his wife at the time of marriage) which you have given them, except when both parties fear that they would be unable to keep the limits ordained by Allah (e.g. to deal with each other on a fair basis). Then if you fear that they would not be able to keep the limits ordained by Allah, then there is no sin on either of them if she gives back (the Mahr or a part of it) for her Al-Khul' (divorce). These are the limits ordained by Allah, so do not transgress them. And whoever transgresses the limits ordained by Allah, then such are the Zalimun (wrong-doers, etc.). 229 If he divorces her finally, she shall not be lawful to him after that, until she marries another husband. If he divorces her, then it is no fault in them to return to each other, if they suppose that they will maintain God's bounds. Those are God's bounds; He makes them clear unto a people that have knowledge. 230 And when you divorce women and they reach their prescribed time, then either retain them in good fellowship or set them free with liberality, and do not retain them for injury, so that you exceed the limits, and whoever does this, he indeed is unjust to his own soul; and do not take Allah's communications for a mockery, and remember the favor of Allah upon you, and that which He has revealed to you of the Book and the Wisdom, admonishing you thereby; and be careful (of your duty to) Allah, and know that Allah is the Knower of all things. 231
