How is the inheritance divided among: a father, a paternal grandfather, a full brother, a mother, a wife, a paternal grandmother, and two full sisters?

The inheritance is divided as follows: The mother receives one-sixth due to the presence of siblings, and the wife receives one-fourth due to the absence of a lineal descendant. The remaining portion goes to the father by way of ta’sib (residuary heirship). The full brother and full sisters, as well as the paternal grandfather, are excluded by the father. The paternal grandmother is excluded by the mother. Thus, the estate is divided into twelve shares: the mother receives two shares, the wife receives three shares, and the father receives seven shares.
