What is the share of the living from the inheritance of a man who passed away, leaving behind two wives and children, in the event that the distribution of the estate was delayed until both wives and some of the children also passed away?

The inheritance of a man, if he leaves no heirs other than those mentioned, and if the two wives have no heirs other than their own children, is divided as follows: The first half of the estate goes to the surviving son from one of the wives. The second half is divided among the living children of the second wife (three sons and one daughter), such that each son receives two shares and the daughter receives one share (dividing the second half into seven shares). The inquirer is advised that matters of inheritance are serious and complex and require review by Sharia courts to achieve the interests of all parties.
