Musnad Abu Ya'la al-Mawsili 245:24

Khalifa ibn Khayyat narrated to us, Abu 'Amir al-'Aqadi narrated to us, Hisham ibn Sa'd narrated to us, from Muhammad ibn 'Uqbah, from Mu'awiyah ibn Abi Sufyan, who said: I heard the Messenger of Allah (peace and blessings of Allah be upon him) saying: "There will be commanders who will not be opposed; they will tumble into the Fire, one following the other."
