What is the ruling on one who runs over a person with his car unintentionally and he dies?

Question: If a man runs over a person with his car unintentionally and he dies, what is required of him?

Answer: If the death was due to a car accident caused by speeding, falling asleep, or the like, then the driver owes the blood money (diyah) and expiation (kaffarah), and the blood money is the responsibility of the 'asabah (residuary male heirs).
As for if the accident was not caused by the driver in any way, then he owes no compensation, just as if a mount stumbled with its rider and passenger, and the passenger fell and died, and the driver had no cause for its stumbling. And whenever there is a dispute between the car owner and the heirs of the deceased, the reference for that is the Shari'ah court.
