Is it necessary to calculate the inheritance for four sons, twelve daughters, and one wife, taking into account the deceased's will to donate one-third of his wealth to charity?

The will to donate a third of the inheritance is valid, as the Prophet, peace and blessings be upon him, said: "Indeed, Allah has bestowed upon you a charity at your death from a third of your wealth, an increase for you in your deeds." The third is given as charity, and the remainder is divided among the heirs. The wife receives one-eighth due to the presence of a lineal descendant, and the rest 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 160 shares: the wife receives 20 shares, each son receives 14 shares, and each daughter receives 7 shares.
