Musannaf Ibn Abi Shaybah

Hazrat Fudayl says that Ibrahim said regarding the woman who leaves behind her daughter, granddaughter, and mother, and has no male agnate, that for her daughter there are three out of five shares of the wealth, for her granddaughter one fifth of the wealth, and for her mother also one fifth share. This is the decision of Hazrat Ali (may Allah be pleased with him). And regarding this, Hazrat Abdullah (may Allah be pleased with him) gave the decision that this issue will be calculated from twenty-four shares: for the granddaughter one sixth, that is, a total of four shares; for the mother one fourth of the remaining wealth, that is, a total of five shares; and for the daughter three fourths of twenty shares, that is, a total of fifteen shares. And regarding this, Hazrat Zaid (may Allah be pleased with him) gave the decision that for the daughter there is half of the wealth, for the granddaughter one sixth of the wealth, and for the mother also one sixth, and the remaining wealth is for the Bayt al-Mal if there is neither a guardian nor any male agnate present.
