How is the estate of a deceased father divided among his two wives and their children, and who are the legal heirs and who are not, and what is the share of each heir?

If a man dies leaving two wives, four sons, six daughters, and one granddaughter, with no other heirs, then his two wives receive one-eighth of the inheritance, to be divided equally between them, due to the presence of children. The remainder is to be divided among the sons and daughters, with the male receiving the share of two females. The granddaughter receives nothing because she is excluded by the direct sons.

The inheritance is divided into 16 shares: two shares for the two wives (one share for each), two shares for each son, and one share for each daughter.

It is important to note that inheritance matters are serious and complex and should be referred to Sharia courts for investigation to ensure there are no wills, debts, or other rights that take precedence over the rights of the heirs.
