Divorce can be pronounced two times; in which case wives may be retained with correctness and courtesy or released with good will. It is not lawful for you to keep anything you have given them unless a couple fear that they will not remain within Allah’s limits. If you fear that they will not remain within Allah’s limits, there is nothing wrong in the wife ransoming herself with some of what she received. These are Allah’s limits, so do not overstep them. Those who overstep Allah’s limits are wrongdoers.
