How is the inheritance divided among three full brothers, a mother, and two full sisters?

If the deceased left behind only a mother, full brothers, and full sisters, then the mother receives one-sixth due to the presence of siblings, based on the Almighty's saying: "And if he has brothers [and sisters], the mother will have a sixth." The remainder goes to the full brothers and sisters by way of ta'sib (agnatic inheritance), with the male receiving the share of two females, based on the Almighty's saying: "And if they are brothers and sisters, male and female, then the male will have the share of two females." The inheritance is divided into 48 shares: the mother receives 8 shares, each full brother receives 10 shares, and each full sister receives 5 shares. Inheritance matters should be referred to the Sharia courts for investigation.
