How is an inheritance divided among a wife, two sons, a full brother, four full sisters, and eight sons of a full brother?

If the heirs are limited to those mentioned, the wife receives one-eighth due to the presence of a lineal descendant, based on the Almighty's saying: "But if you have a child, then for them is one eighth of what you leave." The remainder goes to the two sons by way of ta'sib (residuary heirship), based on the Prophet's (peace be upon him) saying: "Give the prescribed shares to those who are entitled to them, and whatever remains is for the closest male heir." There is nothing for the full sisters, the full brother, or the nephews (sons of the full brother), as they are excluded by the son with an exclusion of deprivation. The estate is divided into sixteen shares: the wife receives two shares, and each son receives seven shares. It is advisable to refer matters of inheritance to the Sharia courts to verify the existence of other heirs, wills, or debts that take precedence over the rights of the heirs.
