It is narrated about Sayyiduna Zubair (may Allah be pleased with him) that on the day of Khaybar, a Jew challenged for single combat, so the Messenger of Allah (peace and blessings be upon him) said: "O Zubair! Go out to face him." Sayyidah Safiyyah (may Allah be pleased with her) said: "O Messenger of Allah! He is my only son." The Prophet (peace and blessings be upon him) said: "Yes." So Sayyiduna Zubair (may Allah be pleased with him) went out to face him and killed him, then the Messenger of Allah (peace and blessings be upon him) gave his belongings as a reward to Sayyiduna Zubair.
