How is the inheritance divided if the heirs are: a mother, three full sisters, and eight sons?

If the deceased's heirs are only sons and a mother, the mother inherits one-sixth due to the presence of a lineal descendant, based on the Almighty's saying: "And for his parents, each of them gets a sixth of what he leaves if he has a child." The remainder goes to the sons by ta'sib (residuary inheritance), based on the saying of the Messenger of Allah, peace be upon him: "Give the prescribed shares to those entitled to them, and whatever remains is for the closest male heir." The inheritance is divided into 48 shares: the mother receives eight shares, and each son receives five shares.
