Musannaf Ibn Abi Shaybah 33280 — A Muslim woman who left her Muslim

Abu Bakr (Ibn Abi Shaybah) said: According to what the Companions of the Prophet (peace and blessings be upon him) other than Sayyiduna Abdullah (may Allah be pleased with him) judged, it is four shares, and they are for the residuary heirs ('asabah); and according to the judgement of Sayyiduna Abdullah (may Allah be pleased with him), it is five shares, and they are for those who become residuary heirs through kinship. Abu Bakr said: According to the statement of all of them, this issue is worked out from six shares: if according to the statement of Sayyiduna Abdullah (may Allah be pleased with him), the mother gets a sixth and five shares remain; and if according to the statement of the Companions of the Prophet (peace and blessings be upon him), the mother gets a third, which is two shares, and four shares are for the other residuary heirs.
