How is the monthly rental sum of 3900 Riyals divided among the heirs of the deceased, who are two wives, 8 sons, and 10 daughters, knowing that the deceased's parents passed away before him? Do his siblings also inherit (full brother, paternal half-sisters, maternal half-brother and half-sister)?

The rent from real estate and other assets of the deceased is divided among their heirs, who are their children and their two wives (if there are two). The two wives receive one-eighth, divided between them, due to the presence of children. The remainder is divided among the sons and daughters by ta'sib (agnatic inheritance), with the male receiving the share of two females. The matter of estates must be referred to the Sharia courts for investigation to ensure there are no wills, debts, or other rights that take precedence over the heirs' rights.
