What is the inheritance share for a brother and two sisters from their deceased sister who had no children, and their other deceased sister?

If the deceased sister has no other heirs besides her living siblings, then her estate is divided among them, with the male receiving the share of two females. The brother receives half, and each sister receives a quarter. There is nothing for the deceased sister, because a condition of inheritance is the life of the heir after the death of the inheritee. Allah Almighty said: (And if there are brothers and sisters, male and female, then the male will have the share of two females. Allah makes clear to you so that you do not go astray. And Allah is knowing of all things.)
