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 ye have divorced your women, and they have attained their period, then either retain them reputably or let them off kindly; and retain them not to their hurt that ye may trespass; and whosoever doth this assuredly wrongeth his soul. And hold not Allah's commandments in mockery and remember Allah's favour upon you, and that he hath sent down unto you the Book and the wisdom wherewith He exhorted you; and fear Allah, and know that verily Allah is of everything the Knower 231
