How are 30,0 Saudi Riyals to be divided among 7 sons, 2 daughters, and their mother, and what is the share of each of them?

If a man passes away leaving only a wife and seven children, the wife receives one-eighth due to the existence of inheriting offspring. The remainder is divided among the children, with the male receiving the share of two females. The total amount is divided into 128 shares: the wife receives 16 shares, each son receives 14 shares, and each daughter receives 7 shares. Inheritance matters must be referred to Sharia courts to verify the absence of any other heirs, wills, or debts that take precedence over the rights of the inheritors.
