A woman who left her paternal half-sister and her full sister

Fudayl said that Ibrahim said concerning a woman who leaves behind one full sister and one paternal half-sister, and has no residuary heir ('asabah) other than them: for her full sister is three quarters of the estate, and for her paternal half-sister one quarter; this is the judgement of Sayyiduna Ali (may Allah be pleased with him). And in this case Sayyiduna Abdullah (may Allah be pleased with him) gave the judgement that for the full sister are five shares and for the paternal half-sister a sixth of the estate. And in this case Sayyiduna Zayd (may Allah be pleased with him) gave the judgement that for the full sister are three shares and for the paternal half-sister a sixth, and the rest is for the public treasury (Bayt al-Mal) when there is no patron (mawla) or residuary heir.

Abu Bakr (Ibn Abi Shaybah) said: According to the statement of Sayyiduna Ali (may Allah be pleased with him), this issue is worked out from three shares, and according to the statement of Sayyiduna Abdullah and Sayyiduna Zayd (may Allah be pleased with them), from six shares.
