What is the legitimate Islamic method for distributing our father's inheritance, which was in the possession of the eldest brother before his imprisonment, then his disappearance in Syria, given that he had distributed some amounts to certain heirs, and spent other amounts on the maintenance and construction of some buildings, knowing that the number of heirs is seven male siblings – one of whom is missing and has offspring – and six female siblings?

The inheritance funds must be confined and distinguished from the brother's money, along with adding what was paid to some heirs. The inheritance is to be divided among sons and daughters, with the male receiving the share of two females (20 shares: each son gets two shares, and each daughter gets one share). The share of the missing son is to be held until his return or a ruling on his death. What the brother paid to some heirs is to be deducted from the recipient's share; if it was less, it should be supplemented, and if it was more, the excess should be returned. Expenses for maintaining inherited buildings are to be borne by all heirs, each according to their share of the inheritance. Finally, matters of inheritance must be referred to Sharia courts or discussed with knowledgeable scholars to ensure that all rights, bequests, and debts are fulfilled.
