How is the inheritance divided between a mother, a paternal grandmother, a full sister, a half-sister through the father, and a full paternal uncle?

If the deceased left only the mentioned individuals, the mother receives one-sixth due to the presence of a group of sisters. The full sister receives one-half, and the paternal sister receives one-sixth to complete the two-thirds. The remaining portion goes to the full paternal uncle by 'asabah (agnatic inheritance). The grandmother receives nothing as she is excluded by the mother. The inheritance is divided into six shares: one share for the mother, three shares for the full sister, one share for the paternal sister, and one share for the full paternal uncle. Matters of inheritance must be referred to the Sharia courts due to their serious nature.
