How is inheritance distributed between a full brother and three full sisters?

If the deceased leaves no heirs except for a full brother and three full sisters, then the inheritance is divided among them by ta'sib (residuary heirship), with the male receiving the share of two females, in accordance with the Almighty's saying: "And if they are brothers and sisters, male and female, then for the male is the share of two females." Thus, the inheritance is divided into five shares: two shares for the full brother, and one share for each full sister. It is advisable to consult the Sharia courts regarding matters of inheritance due to potential complexities such as the existence of other heirs, wills, or debts that take precedence over the heirs' rights.
