What is the share of the two daughters and the children of the deceased son (males and females), and does the full brother's son inherit?

The estate of the deceased woman is divided as follows: her two daughters receive two-thirds, and her grandchildren (the sons of her deceased son) receive the remaining one-third, to be divided among them such that the male receives the share of two females. The brother's son receives nothing, as he is excluded by the sons of the son. Inheritance cases must be submitted to the Sharia courts to verify all rights, debts, and bequests before division.
