Is it permissible for a worker to receive compensation from the employer if he sustains an injury during work that leads to his death, and is this permissible even if it was due to gross negligence on the part of the worker?

If a worker is injured due to the employer's negligence in safety procedures, the employer is obligated to compensate the worker or their heirs, as the Prophet, peace and blessings be upon him, said: "There shall be no harm nor reciprocating harm," and "Harm must be removed." However, if the injury was not due to the employer's negligence, or if it was due to a grave error on the part of the worker, then the employer is not obligated to compensate.
