What is the share of each heir from the inheritance, taking into account the deceased's will concerning the grandchildren?

A bequest to a non-heir, equivalent to the share of a specific heir, is valid. If the deceased bequeathed to his grandchildren a share similar to that of their fathers (six male children and one daughter), and the heirs are two wives, six sons, and one daughter, then the resolution of the matter differs based on whether the heirs approve the bequest or not. If the heirs approve the entire bequest, the inheritance is divided into 320 shares: the two wives receive 26 shares, each living son receives 28 shares, the daughter receives 14 shares, and each of the four grandchildren receives 28 shares for each paternal or maternal grandparent. However, if the heirs do not approve the bequest, the legatees are entitled to only one-third, and the inheritance is divided into 312 shares: the legatees receive 104 shares, which are divided equally among them, the two wives receive 26 shares, each son receives 28 shares, and the daughter receives 14 shares. It is necessary to consult the Sharia courts to resolve inheritance issues.
