Musannaf Ibn Abi Shaybah 33378 — When he leaves his grandfather

Abu Bakr (Ibn Abi Shaybah) said: This case works out from ten shares according to the statement of Sayyiduna Zayd (may Allah be pleased with him), from two shares in the view of Sayyiduna Abdullah (may Allah be pleased with him) and from four shares in the view of Sayyiduna Ali (may Allah be pleased with him); and Sayyiduna Ali (may Allah be pleased with him) used to work it out from six shares when the brothers were many.
