Inheritance of the one who caused the deceased's death

Q: My father was seventy years old. One day, I accompanied him to Najran. He was sitting beside the right door of the car. His headband fell out of the car out onto the road. When the headband fell, he said: "Stop here!" (Part No. 16; Page No. 564) I was driving my car at seventy kilometers per hour, and as I was preparing to stop, he said: "I am getting out of the car." Before finishing his words, he jumped from the car. There were two people sitting between him and me, and I did not notice him opening the door except after he fell on the ground. He died as a result of this accident. After his death, I went to some knowledge seekers who told me that the heirs were not allowed to settle this matter. I fear that I may be one of the three categories that will be deprived of inheritance. The police of Najran investigated the accident, and I have to pay 25% from the blood money and to observe Sawm (Fast) for two consecutive months. The rest of the heirs waived their shares in the blood money. I would like Your Eminence to give me a written Fatwa if I can inherit from my father or not.

A: If the reality is as you have mentioned, you will be permitted to have your share of inheritance from your father and you will not be required to offer any expiation, as we do not see any hindrance that prevents you from inheriting your father, as he is the reason behind killing himself. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
