How is an inheritance divided among a father, a wife, two daughters, a son's daughter, and six full brothers?

If the deceased left behind only a father, a wife, two daughters, full siblings, and a son's daughter, then the father receives one-sixth as a fixed share due to the presence of a lineal descendant heir. His wife receives one-eighth as a fixed share due to the presence of a lineal descendant heir. His two daughters receive two-thirds as a fixed share. The father takes the remainder by ta'sib (residuary heirship). The full siblings receive nothing because they are excluded by the father. The son's daughter receives nothing because the daughters have exhausted the two-thirds share. The estate is divided into twenty-four shares: the wife receives three shares, the two daughters sixteen shares, and the father five shares. Issues related to estates must be referred to Sharia courts for investigation.
