How is an inheritance divided among three sons, three daughters, and a granddaughter (daughter of a son)?

If a person dies leaving only sons and daughters, their inheritance is divided among them, with the male receiving the share of two females, in accordance with Allah's saying: (Allah instructs you concerning your children: for the male, what is equal to the share of two females). The inheritance is divided into nine shares: each son receives two shares, and each daughter receives one share. The granddaughter does not inherit because she is excluded by the direct sons and daughters. Issues concerning inheritances must be brought before the Sharia courts for investigation, as there may be wills, debts, or rights that take precedence over the heirs' rights.
