Al-Adab Al-Mufrad #848

Usama ibn Zayd reported that the Messenger of Allah, may Allah bless him and grant him peace, arrived at a gathering which included 'Abdullah ibn Ubayy ibn Salul before 'Abdullah ibn Ubayy had become Muslim. He said, "Do not bother us in our gathering." The Prophet, may Allah bless him and grant him peace, went to Sa'd ibn 'Ubada and said, "Sa'd, did you not hear what Abu Hubab said?" He meant 'Abdullah ibn Ubayy ibn Salul.
