Musannaf Ibn Abi Shaybah 33576 — Those who said: a Muslim does not

Maymun bin Mihran says that al-Urs bin Qays al-Kindi asked me by letter about two Christian brothers, one of whom becomes a Muslim while the other dies and leaves property. I said that Sayyiduna Mu'awiyah (may Allah be pleased with him) used to say: "If that brother were a Christian he would inherit, and Islam has added nothing to him but strength." Al-Urs bin Qays says that Sayyiduna Umar (may Allah be pleased with him) refused us this in the case of the Jewish paternal aunt of al-Ash'ath bin Qays, and did not make him her heir.
