How is the inheritance divided among the wife, the son, and the daughter?

If the deceased leaves behind only his wife, a son, and a daughter, then the wife receives one-eighth due to the presence of a legal heir, as Allah Almighty says: "But if you have a child, then for them [the wives] is one eighth of what you leave, after any bequest you [may have made] or debt." The remainder is for the son and the daughter by way of ta'sib (residuary heirship), with the male receiving the share of two females, as Allah Almighty says: "Allah instructs you concerning your children: for the male, what is equal to the share of two females." The inheritance is divided into twenty-four shares: the wife receives three shares, the son fourteen shares, and the daughter seven shares. The matter of inheritances must be submitted to the Sharia courts to verify the existence of other heirs, bequests, or debts that take precedence over the rights of the heirs.
