Sa'd ibn Ubadah
Abdullah ibn Ubayy encouraged rumours that Muhammad's wife Aisha had committed adultery. Muhammad addressed the Muslims in the mosque about it: "Why do certain men lie about my family?" An Aws leader, Usayd ibn Hudayr, replied: "If they are of Aws let us rid you of them; and if they are of the Khazraj give us your orders, for they ought to have their heads cut off." Sa'd ibn Ubadah stood up and retorted: "By Allah, you lie. They shall not be beheaded. You would not have said this if you had not known that they were of Khazraj. If they had they been your own people, you would not have said it."
