Ruling on someone who cannot drive well who ran a person over and ran away

A: If it is more likely that you caused the death of the man, you will be liable to the Kaffarah (expiation) of accidental killing, which is freeing a Muslim slave or, if it is not feasible, fasting for two consecutive months, i.e. sixty days. Moreover, your family will be liable to the Diyah (blood money) of the man supposing it was a Muslim country where the accident took place. If the family cannot pay it, you have to pay it yourself to the man's legal heirs, whom you have to search for. However, if you cannot find them, you should give the money in charity on their behalf.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
