Musannaf Ibn Abi Shaybah 33373 — A woman who left her full sister

Ibrahim said: For a woman who leaves behind her full sister and her grandfather, half of the wealth is for her full sister, according to the statement of Sayyiduna Ali and Sayyiduna Abdullah (may Allah be pleased with them both). And Sayyiduna Zayd (may Allah be pleased with him) used to give the sister a third of the wealth and the grandfather two thirds of the wealth.
