Parking the car on a slope which moved and killed someone by mistake

Q: Around ten years ago, my car had a problem and I parked it in a high place to be able to jerk and operate it. I checked my car's water and released the gearbox as I thought that doing so would warm the car even though it was not operating. I was old and ignorant of cars' mechanics. Suddenly my car rushed quickly towards my grandson. I tried to stop it but it dropped me down, ran over my grandson and caused him to die. I hope that your Eminence will issue a Fatwa for me in this regard.

A: If the reality is exactly as you have mentioned, it will be obligatory (Wajib) on you to make Kaffarah (expiation) of involuntary manslaughter. Such a Kaffarah is to free a believing slave or, if you are unable to do so, to observe Sawm (Fast) for two successive months because you are the one who caused the accident. Regarding the Diyah (blood money), if there is a claim it will have to be decided by the court. (Part No. 21; Page No. 301) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
