Musannaf Ibn Abi Shaybah 33412 — How many grandmothers inherit?

Fudayl said that Ibrahim said: The grandmothers will inherit a sixth share of the estate. If there are one, two or three of them, then according to the saying of Sayyiduna Ali (may Allah be pleased with him) and Sayyiduna Zayd (may Allah be pleased with him), a single share will be divided between them. And when three grandmothers come together, each of them equal in relationship to the deceased, a single share will be divided between them: a grandmother from the mother's side and a grandmother from the father's side, the mother of his father and the mother of his mother. And Sayyiduna Abdullah (may Allah be pleased with him) said: When three grandmothers come together, a sixth share of the estate will be divided between them, even if some of them are nearer in lineage to the deceased, provided that none of them is the mother of another.
