A Muslim woman who left her Muslim mother, and has Christian, Jewish or disbelieving brothers

Fudayl reports that Ibrahim said concerning a Muslim woman who leaves behind her Muslim mother, while she has Christian, Jewish or disbelieving brothers: Sayyiduna Abdullah (may Allah be pleased with him) gave the judgement that in the presence of these people she is to receive a sixth, and he treated them as barring the share of others while not making them heirs themselves. And the rest of the Companions of the Prophet (peace and blessings be upon him) gave the judgement on this issue that they neither reduce the share of others nor inherit themselves.

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.
