Musannaf Ibn Abi Shaybah 33408 — How many grandmothers inherit?

Yunus narrates from al-Hasan that he used to make three grandmothers heirs and would say: Whichever of them is nearer, the estate will be given to her and not to the other grandmothers; and when the grandmothers are of equal degree, the estate will be divided between them.
