How much is the share of each heir from the inheritance, which amounts to 4800 Riyals, if the deceased passed away leaving behind a mother, six maternal half-siblings, and fifteen paternal half-siblings?

If the heirs are limited to those mentioned, the mother receives one-sixth due to the presence of siblings. The siblings from the mother's side receive one-third, and what remains goes to the siblings from the father's side, based on the Almighty's saying: "And for his parents, each of them the sixth of what he left if he had a child; but if he had no child and his parents inherited him, then for his mother is the third; and if he had siblings, then for his mother is the sixth," and the Almighty's saying: "And if a man or a woman leaves no direct heir but has a brother or a sister, then for each one of them is the sixth; and if they are more than that, then they are sharers in the third," and the Hadith (definition): "Give the prescribed shares to those entitled to them, and what remains is for the closest male heir."
