What is the share of each heir from the inheritance, knowing that one of the deceased's sons is mentally ill, and that his first wife was separated from him before his death and refused divorce?

To the father goes one-sixth, and to the two wives goes one-eighth. The remainder is for the sons and the daughter, with the male receiving the share of two females. The inheritance is divided into 336 shares: the father receives 56 shares, the two wives receive 42 shares (21 shares for each), each son receives 68 shares, and the daughter receives 34 shares. The illness of the son and the wife not residing in her husband's house do not affect their entitlement. It is necessary to consult the Sharia courts regarding matters of inheritance, as there may be other rights that take precedence over the heirs' rights.
