Musannaf Ibn Abi Shaybah 33344 — A husband, a mother, brothers

Ibrahim said: Sayyiduna Abdullah (may Allah be pleased with him) used to work out the case of "al-Akdariyyah" from eight shares: three shares for the husband, three shares for the sister, one share for the mother and one share for the grandfather. He said: Sayyiduna Ali (may Allah be pleased with him) used to work out this case from nine shares: three shares for the husband, three shares for the sister, two shares for the mother and one share for the grandfather. And Sayyiduna Zayd (may Allah be pleased with him) also used to work out this case from nine shares: three shares for the husband, three shares for the sister, two shares for the mother and one share for the grandfather. Then he would multiply it by three, so that there are 27 shares in all. In this way he would give the husband nine shares and the mother six shares; 12 shares remain, and he would give the grandfather eight shares and the sister four shares.
