Divorce may be pronounced twice; then either the wife be kept honourably or parted with gracefully. And it is not lawful for you to take back anything out of what you have given them. There is, however, an exception to this; if you fear that they might not be able to keep within the limits imposed by Allah, there is no harm if both agree mutually that the wife should obtain divorce by giving something as compensation to the husband. These are the bounds set by Allah; therefore do not violate them, for those who violate the bounds of AIIah are the tansgressors.
