Abu Dawud Book 18, Hadith Number 3624.

Narated By Mu’awiyah al-Qushayri : Bahz ibn Hakim reported from his grandfather: (Ibn Qudamah’s version has: His grandfather’s brother or uncle reported:) – the narrator Mu’ammal said: – He (his grandfather Mu’awiyah) got up before the Holy Prophet (PBUH) who was giving sermon: and he said: Why have your companions arrested my neighbours? He turned away from him twice. He (his grandfather Mu’awiyah) then mentioned something. The Holy Prophet (PBUH) then said: Let his neighbours go.

(Mu’ammal did not mention the words “He was giving sermon.”)
