Sulayman bin Yasar (may Allah have mercy on him) said that the paternal aunt of Muhammad bin al-Ash'ath was a Jew or a Christian, and she died. Muhammad bin al-Ash'ath mentioned this to Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) and asked: Who inherits from her? Sayyiduna Umar (may Allah be pleased with him) said: The people of her religion inherit from her. Then he came to Sayyiduna Uthman bin Affan (may Allah be pleased with him) and asked him about it. Sayyiduna Uthman (may Allah be pleased with him) said: Do you think I have forgotten what Umar said to you? Then he said: The people of her religion inherit from her.
