Divorce can happen twice, and [each time] wives either be kept on in an acceptable manner or released in a good way. It is not lawful for you to take back anything that you have given [your wives], except where both fear that they cannot maintain [the marriage] within the bounds set by God: if you [arbiters] suspect that the couple may not be able to do this, then there will be no blame on either of them if the woman opts to give something for her release. These are the bounds set by God: do not overstep them. It is those who overstep God’s bounds who are doing wrong.
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 Allâh (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 Allâh, 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 Allâh, so do not transgress them. And whoever transgresses the limits ordained by Allâh, then such are the Zâlimûn (wrong-doers).
