Maymun bin Mehran says that ‘Urs bin Qais Kindi asked me by letter about two Christian brothers, one of whom became Muslim and the other died and left wealth. I said that Hazrat Muawiyah (may Allah be pleased with him) used to say that if that brother had remained Christian, he would have been an heir, and Islam has added nothing to this except strictness. ‘Urs bin Qais says that Hazrat Umar (may Allah be pleased with him) rejected this matter regarding the Jewish aunt of Ash’ath bin Qais and did not make her an heir.
