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 So if a husband divorces his wife (irrevocably), He cannot, after that, re-marry her until after she has married another husband and He has divorced her. In that case there is no blame on either of them if they re-unite, provided they feel that they can keep the limits ordained by Allah. Such are the limits ordained by Allah, which He makes plain to those who understand. 230 And when you have divorced your wives and they are about to complete their prescribed term, then either retain them gracefully or release them generously. It is transgression to retain them merely for harassment; and whoever' does that indeed wrongs his own self. Do not play with Allah's Commandments, and remember that Allah has blessed you with a great favour. He admonishes you to show due respect to the Book and the Wisdom He has sent to you. Fear Allah and know that He is fully aware of everything. 231
