How is inheritance divided among four sons, two daughters, a wife, and the deceased's full sister?

If the heirs are limited to those mentioned, the wife receives one-eighth due to the existence of a inheriting offspring, as Allah Almighty says: ﴿But if you have a child, then for them is one-eighth of what you leave, after any bequest you [may have] made or debt.﴾ [An-Nisa: 12]. The remainder goes to the sons and daughters by ta'sib (residuary heirship), with the male receiving the share of two females. The inheritance is divided into eighty shares: the wife receives one-eighth (10 shares), each son receives 14 shares, and each daughter receives 7 shares. As for the sister, she does not inherit, as she is completely excluded from inheritance due to the presence of sons. The matter of inheritances must be referred to the Sharia courts for investigation, as there might be another heir, bequests, debts, or other rights that take precedence over the rights of the heirs.
