Hazrat Yazid bin Alqamah (may Allah have mercy on him) narrates that a man from Banu Taghlib, whose name was Ubadah bin Nu'man, had a wife from Banu Tamim. That woman accepted Islam, so Hazrat Umar (may Allah be pleased with him) called her husband and said, "If you wish, accept Islam; otherwise, we will separate your wife from you." He refused to accept Islam, so Hazrat Umar (may Allah be pleased with him) separated his wife from him.
