What is the ruling on benefiting from work injury insurance, which covers natural death, and whose premiums are not deducted from the salary, when an injury occurs without death? And is it permissible for the heirs to take the insurance amount in the event of death? And what must the beneficiary do after learning of this?

There is no objection to benefiting from the compensation provided by the employer to an injured worker during work, or from the pension disbursed to him, whether directly from the employer or through an insurance company. The sin, if any, rests with the employer, not with the worker or his heirs, because he is entitled to it.
