How are the blood money payments (diyat) divided for two unmarried brothers who died in a car accident, whose heirs are their father who died hours after them, and their mother, knowing that the father's heirs are his mother, his wife, two sons, and five daughters?

Firstly: The inheritance of the two brothers is distributed to the father and mother only; the mother receives one-sixth and the father receives the remainder, based on the Almighty’s saying: (And for his parents, each of them gets a sixth of what he leaves if he has a child; but if he has no child and his parents inherit from him, then his mother gets a third; and if he has brothers, then his mother gets a sixth, after any bequest he may have made or any debt).

Secondly: Then, the estate of the father (what he received from the blood money of the two brothers, along with his own blood money, and his other assets) is distributed among his heirs: the mother receives one-sixth, based on the Almighty’s saying: (And for his parents, each of them gets a sixth of what he leaves if he has a child); and the wife receives one-eighth, based on the Almighty’s saying: (but if you have a child, then they get an eighth of what you leave); and the remainder is distributed among the children, with the male receiving the share of two females, based on the Almighty’s saying: (Allah instructs you concerning your children: for the male, the share of two females).
