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 And if he has divorced her (the third time), then she is not lawful unto him thereafter until she has married another husband. Then, if the other husband divorces her, it is no sin on both of them that they reunite, provided they feel that they can keep the limits ordained by Allah. These are the limits of Allah, which He makes plain for the people who have knowledge. 230 And so, when you divorce women and they are about to reach the end of their waiting-term, then either retain them in a fair manner or let them go in a fair manner. But do not retain them against their will in order to hurt [them]: for he who does so sins indeed against himself. And do not take [these] messages of God in a frivolous spirit; and remember the blessings with which God has graced you, and all the revelation and the wisdom which He has bestowed on you from on high in order to admonish you thereby; and remain conscious of God, and know that God has full knowledge of everything. 231
