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 divorces her [finally,] she shall thereafter not be lawful unto him unless she first takes another man for husband; then, if the latter divorces her, there shall be no sin upon either of the two if they return to one another - provided that both of them think that they will be able to keep within the bounds set by God: for these are the bounds of God which He makes clear unto people of [innate] knowledge. 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
