A man caused a traffic accident in which he died and others died, and the traffic department said the cause of the accident was?

Question:
Honorable Shaykh, may Allah grant you success. A man died as a result of a traffic accident, and the owner of the second car also died. The traffic department said the cause of the accident was the dust that occurred on the day of the accident. The question is: Is there any fasting or freeing of a slave required of the father? Knowing that the heirs of both parties have waived the blood money?

Answer:
By Allah, this returns to the court, because the traffic report is submitted to the judge, and he rules on it regarding conviction or non-conviction for killing. We cannot issue a fatwa on this; follow the courts. Yes.
