(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 (ﷺ) 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 (ﷺ) then said: Let his neighbours go.

(Mu'ammal did not mention the words "He was giving sermon.")
