Is the uncle's division of the inheritance valid, and is it permissible to divide the deceased father's share of 28,0 Riyals?

If the house price is 70,0 Saudi Riyals, it is divided according to the rule of a male receiving the share of two females. Thus, each son receives 28,0 Riyals and each daughter receives 14,0 Riyals. The father's share (28,0 Riyals) is then divided among his heirs: the wife receives one-eighth (3,500 Riyals), and the remaining amount (24,500 Riyals) is divided among the children, with a male receiving the share of two females. So, each son receives 6,125 Riyals and each daughter receives 3,62.5 Riyals. The paternal aunt's share (14,0 Riyals) is divided among her heirs: the husband receives one-fourth (3,500 Riyals), and the remainder is divided among the children, with a male receiving the share of two females. So, each son receives 1,750 Riyals and each daughter receives 875 Riyals.
