How is inheritance divided among: a father, a mother, a wife, 3 full brothers, 3 full sisters, 6 full nephews, and 15 full paternal cousins?

The inheritance is divided as follows: the wife receives one-fourth as a prescribed share, and the mother receives one-sixth due to the presence of a group of siblings. The remainder goes to the father, both as a prescribed share and by agnatic inheritance. The rest of the relatives do not inherit due to the father's presence. The inheritance is divided into twelve shares: the wife receives three shares, the mother receives two shares, and the remainder goes to the father. It is recommended to refer inheritance matters to the Sharia courts, as there might be wills, debts, or other rights.
