What is the ruling of Islamic law concerning mandatory car accident insurance, what is the ruling concerning the insured party who is forced to conclude the contract, what is the ruling concerning the insurer, and what is the ruling concerning the injured party receiving compensation from the insurance company?

It is permissible for someone compelled to participate in forbidden commercial insurance to insure for the minimum legally required amount, and the sin for this falls upon whoever compelled him.

It is also permissible for the wronged party to receive the compensation amount from the insurance company instead of receiving it from the one who caused the damage, because the wronged party is not responsible for money earned by another, if it is given to him in exchange for his legitimate entitlement to that money.
