Musannaf Ibn Abi Shaybah 32799 — A bequest to a Jew or a Christian

Yahya bin Sa'id said: It reached me that Sayyidah Safiyyah (may Allah be pleased with her) made a bequest of a great deal of wealth to relatives of hers among the Jews, who would have been her heirs had they been Muslims; but because of their being disbelievers, the Muslims of her family inherited from her. Therefore her bequest was carried out in favour of those who were not Muslims.
