How is the inheritance divided among 12 full brothers of the deceased and two full sisters of the deceased?

For the two full sisters, two-thirds is an obligatory share, based on the Almighty's saying: "But if there are two [sisters], they shall have two-thirds of what he leaves." The remainder goes to the sons of the full brother by way of ta'sib (residuary heirship), based on the Prophet, peace and blessings be upon him, saying: "Give the obligatory shares to those who are entitled to them; then whatever remains is for the closest male relative." The inheritance is thus divided into thirty-six shares: the two sisters receive two-thirds of it (24 shares), with twelve shares for each, and each son of the full brother receives one share. The matter of inheritances must be referred to the Sharia courts, as there might be other heirs, wills, or debts that take precedence over the rights of the heirs.
