Musnad Abu Ya'la al-Mawsili 245:11

'Uthman ibn Abi Shaybah narrated to us, he said: I heard Jarir saying: I heard an old man narrating to Mughirah, from the daughter of Hisham ibn al-Walid ibn al-Mughirah, and she used to nurse 'Ammar. She said: Mu'awiyah came to 'Ammar to visit him. When he left from his presence, he said: "O Allah, do not make his death at our hands, for I heard the Messenger of Allah (peace and blessings of Allah be upon him) saying: 'The rebellious group will kill 'Ammar.'"
