Musnad Ahmad 1034:83

Hassan narrated to us, from Hammad ibn Salamah, from Hammad ibn Abi Sulayman, from Rib'i ibn Hirash, from Hudhayfah ibn al-Yaman, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "A people will emerge from the Fire after the Fire has scorched them. They will be called: 'The Jahannamiyyun' (the Hell-dwellers)."
