What is the ruling on the money I received from the insurance company as a result of my claim that the injury occurred during work, even though it was outside of work? And how can I return the money that I do not rightfully deserve to the insurance company?

It is permissible for an employee to receive injury compensation from the company that contracted for the insurance, and this is considered a gift from the company to its employees. There is no sin upon the employee if the insurance is commercial; rather, the sin is upon the company. However, if the employee claims that an injury sustained outside work occurred within work to receive higher compensation, he must return the difference to the insurance company or inform them of the reality of the situation. The statute of limitations for the injury does not negate the employee's right to compensation.
