Harun bin al-Asamm (may Allah have mercy on him) said that Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) sent Khalid bin al-Walid (may Allah be pleased with him) with an army, and Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) sent Dirar bin al-Azwar (may Allah be pleased with him) with a party of horsemen. They raided (a clan of) Banu Asad and captured a beautiful bride. Dirar (may Allah be pleased with him) liked her, and with the consent of his companions Dirar (may Allah be pleased with him) had intercourse with her. When they returned, he was ashamed and filled with regret. When he was brought to Khalid bin al-Walid (may Allah be pleased with him) and informed him of what he had done, Sayyiduna Khalid (may Allah be pleased with him) said: I declare this woman permissible for you. He said: No, rather write to Sayyiduna Umar bin al-Khattab (may Allah be pleased with him). So Sayyiduna Umar (may Allah be pleased with him) wrote that his head should be crushed with stones. When Sayyiduna Umar's (may Allah be pleased with him) letter arrived, he had already died. The narrator said: Allah Almighty saved Dirar bin al-Azwar (may Allah be pleased with him) from disgrace.
