How is the inheritance distributed if a grandmother who inherits (e.g., maternal grandmother) is present alongside a paternal grandmother when the father is present, based on the view that the paternal grandmother is veiled by her son?

Primary text
If the one who veils or contends with the maternal grandmother (the paternal grandmother) is removed from consideration because of the father, then the ruling of the veiling/contention is voided, and she becomes as if non-existent. The ruling concerns the inheritance between the maternal grandmother (mother of mother) and the paternal grandmother (mother of father) when the father inherits. If the paternal grandmother is removed by the father's existence (based on the view that the son veils the grandmother), the ruling is affected.

There are differing views on the consequences: one states the entire one-sixth share goes to the most remote maternal grandmother (mother of mother of mother) because the one who veiled her is removed. Another view suggests she receives half the one-sixth, following Zayd's position which permits inheritance from the more distant maternal side alongside the nearer paternal side. A third view states she receives nothing because she was veiled by the paternal grandmother, who was then veiled by the father, resulting in the entire inheritance going to the father.
