Who inherits from a grandmother who has only her son's child and a brother from her mother's side?

If a woman dies and leaves behind only a grandson and a uterine brother, the entire inheritance goes to the grandson, and nothing to the uterine brother; because he is completely excluded by the grandson. If there is more than one grandson, the wealth is divided equally among them if they are all males, and if they are males and females, the male receives the share of two females. It is important to note the seriousness of inheritance matters, and that they should not be divided without consulting the Sharia courts.
