Musannaf Ibn Abi Shaybah 33174 — A husband, a mother, full brothers

Ibrahim said concerning a woman who at her death left her husband, her mother, full brothers and maternal half-brothers: Her husband receives 3 shares, that is, half of the entire wealth; her mother receives 1 share, that is, one-sixth of the entire wealth; and her maternal half-brothers receive 2 shares, that is, one-third of the wealth. He gave this woman's full brothers no share of the inheritance, following the decision of Sayyiduna Ali (may Allah be pleased with him); whereas Sayyiduna Umar, Sayyiduna Abdullah and Sayyiduna Zayd bin Thabit (may Allah be pleased with them) made the full brothers partners with the maternal half-brothers in the one-third of the wealth that they inherited, except that these Companions gave the men and women among them an equal share.
