Musannaf Ibn Abi Shaybah

Fazil Ibrahim narrates that if a man leaves behind his daughter, real sister, and grandfather, then according to the statement of Hazrat Ali (may Allah be pleased with him), his daughter will receive half of the estate, his grandfather will receive one-sixth, and the remainder will be given to his sister. And he (Ali) would not give the grandfather more than one-sixth in the presence of descendants. According to the statement of Hazrat Abdullah (may Allah be pleased with him), his daughter will receive half of the estate, and the remainder will be divided between the sister and the grandfather. And if there are two sisters (instead of one), then according to the statements of Hazrat Abdullah (may Allah be pleased with him) and Zaid (may Allah be pleased with him), the remainder will be divided between the sisters and the grandfather. And according to the statement of Hazrat Ali (may Allah be pleased with him), the grandfather will receive one-sixth of the estate, and the remainder will be for both sisters. And if there are three sisters, along with a daughter and a grandfather, then the daughter will receive half of the estate, and according to the statements of Hazrat Abdullah (may Allah be pleased with him) and Zaid (may Allah be pleased with him), the grandfather will receive two-fifths (2/5) of the remainder, and the sisters will receive the remaining three-fifths. Hazrat Abu Bakr states that this issue, according to the statement of Hazrat Ali (may Allah be pleased with him), will be resolved from ten shares: five shares for the daughter, two shares for the grandfather, and one share each for the sisters.
