How is the inheritance divided among 3 sons, a mother, 7 daughters, and a wife?

If the heirs are limited to those mentioned, then the mother receives one-sixth due to the presence of a lineal descendant, and the wife receives one-eighth due to the presence of a lineal descendant. The remainder is for the sons and daughters by ta'sib (residuary heirship), with the male receiving the share of two females. The inheritance is divided into 312 shares: the wife receives 39 shares, the mother 52 shares, each son 34 shares, and each daughter 17 shares. Issues of inheritance must be brought before the Sharia courts for investigation, as there might be another heir, or wills, or debts, or other rights that take precedence over the rights of the heirs.
