The Diyyah of the Killed is Due on the One Causing the Accident

Answer:

All praise is due to Allah, peace and blessings be upon the Messenger of Allah and upon all his family and companions: If the traffic report has proved that the young man was to blame, then it is accidental killing, and so the person responsible must pay the Diyah. Allah, The Almighty, said: “Never should a believer kill a believer; but (If it so happens) by mistake, (Compensation is due): If one (so) kills a believer, it is ordained that he should free a believing slave, and pay compensation to the deceased’s family, unless they remit it freely. If the deceased belonged to a people at war with you, and he was a believer, the freeing of a believing slave (Is enough). If he belonged to a people with whom ye have treaty of Mutual alliance, compensation should be paid to his family, and a believing slave be freed. For those who find this beyond their means, (is prescribed) a fast for two months running: by way of repentance to God: for God hath all knowledge and all wisdom.”{Al-Nisa`/92}. Accordingly, the Aqilah(male relatives of the killer`s clan from his father`s side)of the young man must pay the Diyah to the heirs of those killed in the accident. And Allah knows best.
