229th Ayah from Surah Al Baqarah
Sahih International
Divorce is twice. Then, either keep [her] in an acceptable manner or release [her] with good treatment. And it is not lawful for you to take anything of what you have given them unless both fear that they will not be able to keep [within] the limits of Allah . But if you fear that they will not keep [within] the limits of Allah, then there is no blame upon either of them concerning that by which she ransoms herself. These are the limits of Allah, so do not transgress them. And whoever transgresses the limits of Allah - it is those who are the wrongdoers.
Abdul Haleem
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.
Mohsin Khan/Hilali
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.).
Taqi Usmani
Divorce is twice; then either to retain in all fairness, or to release nicely. It is not lawful for you to take back anything from what you have given them, unless both apprehend that they would not be able to maintain the limits set by Allah. Now, if you apprehend that they would not maintain the limits set by Allah, then, there is no sin on them in what she gives up to secure her release. These are the limits set by Allah. Therefore, do not exceed them. Whosoever exceeds the limits set by Allah, then, those are the transgressors.
