What is the share of each heir from the deceased's estate, given the presence of a paternal grandfather, a maternal grandmother, a paternal grandmother, and one full sister?

If the heirs are limited to two grandmothers, a grandfather, and a full sister, and the deceased left no other heirs, then the two grandmothers receive one-sixth (1/6) equally between them, as it is established that the Prophet, peace and blessings be upon him, ruled thus. The remainder after the grandmothers' one-sixth is divided between the grandfather and the full sister, with the male receiving the share of two females. This is the fatwa (legal opinion) we follow, which allows siblings to inherit with the grandfather. However, according to the opinion that the grandfather completely disinherits siblings, the grandfather would take the remainder after the grandmothers' one-sixth, and the full sister would receive nothing.
