How is an inheritance divided among four sons, three daughters, a husband, one grandson, and one granddaughter?

If the heirs are limited to the husband, sons, and daughters, the husband receives one-fourth due to the presence of a lineal descendant (heir). The remainder is distributed among the sons and daughters by ta'sib (agnatic inheritance), with the male receiving the share of two females. The son of a son or daughter of a son receives nothing, as they are excluded by the direct son. The inheritance is divided into 44 shares: the husband receives 11 shares, each son receives 6 shares, and each daughter receives 3 shares. Inheritance matters must be referred to the Sharia courts for investigation and to ensure there are no wills, debts, or other rights that take precedence over the rights of the heirs.
