How is the sum of 47,535 Saudi Riyals to be divided among heirs consisting of: one son, a mother, and a wife?

If the deceased leaves behind only a mother, a wife, and a son, then the mother receives one-sixth due to the presence of a lineal descendant (inheritor). Allah the Almighty says: "And for his parents, each of them is to have a sixth of what he leaves if he has a child." (An-Nisa: 11). And his wife receives one-eighth due to the presence of a lineal descendant (inheritor). Allah the Almighty says: "But if you have a child, then for them is an eighth of what you leave, after any bequest you [may have] made or debt." (An-Nisa: 12). The remainder goes to the son by way of ta'sib (residuary inheritance), 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."

The inheritance is divided into 24 shares: 4 shares for the mother, 3 shares for the wife, and the remaining 17 shares for the son.
