Musnad Ahmad 1034:204

Aswad ibn Amir narrated to us, Abu Bakr narrated to us, from Asim, from Abu Wa'il, who said: Hudhayfah said: While I was walking on a road in Medina, he said: Suddenly, the Messenger of Allah, peace and blessings of Allah be upon him, was walking. I heard him say: "I am Muhammad, and Ahmad, and the Prophet of Mercy, and the Prophet of Repentance, and the Gatherer (al-Hashir), and the Successor (al-Muqaffi), and the Prophet of Great Battles (al-Malahim)."
