The Atonement For Accidental Killing

Question :

I was driving in my car and suddenly a man came out crossing the road in front of me, and I was unable to avoid hitting him because he took me by surprise and the car was moving. Thus it happened that he was run over, as a result of which, he died immediately, even though my speed was normal, not excessive, but he committed a violation. For this reason, the Traffic Police reported that he was 50% to blame for the accident and there is no power and no strength except from Allah. Bearing in mind that it has been judged upon me by settlement that his share of the blame was 70% and what remains for me is the atonement, I am requesting a legal verdict. And may peace, mercy and blessings of Allah be upon you.

Answer:

If the situation is as described, then you must make atonement for accidental killing, which is to free a believing slave. If you do not find one, then you must fast for two consecutive months. It is not sufficient for you to do anything else, according to the Words of Allah, Most High:
"and whosoever kills a believer by mistake, (it is ordained that) he must set free a believing slave and compensation (blood money, i.e. Diya) be given to the deceased's family unless they remit it."

Up to His Words :
"And whose finds this (the penance of freeing a slave) beyond his means, he must fast for two consecutive months in order to seek repentance from Allah. And Allah is Ever All-Knowing, All-Wise."

And may peace and blessings be upon our Prophet, Muhammad and upon his family and Companions.
