Is it permissible to benefit from government social insurance to compensate for a work injury that occurred in the private sector, knowing that a portion of the salary has been deducted for medical insurance for 28 years without benefiting from it?

Cooperative insurance is permissible, as is insurance where the state deducts a specific percentage from an employee's income, provided that the deducted funds are not invested in interest-bearing activities, or if the insurance is mandatory. The employee's right to compensation is subject to the contract between them and their employer. If the contract stipulates their right to treatment at the state's expense or compensation for injury, then they are entitled to it. In all cases, they have the right to reclaim what was deducted from their salary.
