Bahz bin Hakim, on his father's authority, said that his grandfather told that the Prophet (ﷺ) imprisoned a man on suspicion.
Sunan Abi Dawud Book 25, Hadith 60
← Previous Hadith I brought my debtor to the Holy Prophet (ﷺ). He said to me: Stick to him. He again said to me: O brother of Banu Tamim, what do you want to do with your prisoner.

Sunan Abi Dawud Book 25, Hadith 59 Next Hadith → (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.")
