Musannaf Ibn Abi Shaybah

Ibrahim narrates that Hazrat Abdullah (may Allah be pleased with him) said regarding the case of a daughter, a sister, and a grandfather that the daughter should be given half of the wealth, and the remaining wealth should be divided equally between the grandfather and the sister. And he was asked about the case of a daughter, two sisters, and a grandfather, so he decided that half of the wealth should be given to the daughter, and the remaining wealth should be divided equally between the grandfather and the two sisters. And on one occasion, he was asked about the case of a daughter, three sisters, and a grandfather, so he decided that the daughter should be given half of the wealth, the grandfather should be given two-fifths of the remaining wealth, and each sister should be given one-fifth.
