Is the plaintiff entitled to claim compensation from the car dealership for impounding his car for five years, knowing that the reason for the impoundment was the plaintiff's refusal to pay for a repair cost that violated the agreement, and that the court ruled in favor of the plaintiff for the return of his car, and the judge is asking him to prove damages despite his purchase of a replacement car?

This issue is a dispute being heard before the court, and the final say on it belongs to the court. However, in general, Islamic legal texts have indicated the permissibility of compensation for damages. If it is proven that the agency transgressed by wrongfully impounding the car and preventing its use, then the questioner has the right to demand compensation for the resulting damage. This damage is assessed by the Sharia (definition) judiciary, and purchasing another car does not negate his right to compensation.
