Distributing the inheritance among people who died in the same accident without knowing who died first

Q: My father, his mother and his sister died in a car accident. The accident report stated that they all died at the same time, and Allah knows best. Knowing that my father had no children except me, I would like to know how my father's estate can be divided. My paternal grandmother who died in this accident had no children except the daughter who also died in the same accident. His sister who died in the same accident had four sons and one daughter. Are they entitled to the estate of my father, his mother and his sister?

(Part No. 16; Page No. 543) A: If the case is as you have mentioned, that your father, your paternal grandmother, and paternal aunt all died in this accident and you do not know who died first, none of them is entitled the other's estate. The living heirs of each deceased person are entitled to their specified shares. May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions!
