Is it permissible, in Islamic law, to enforce a judicial ruling to imprison a brother who withheld inheritance?

Your brother has sinned by oppressing you and withholding your rightful inheritance. There is no sin or blame upon you for enforcing the court's judgment to imprison him. However, it is preferable for you to seek reconciliation with him to avoid his imprisonment, even if it requires waiving a portion of the inheritance, unless pardoning him would lead to corruption.
