Musannaf Ibn Abi Shayba 37:429

Abu Bakr narrated to us, he said: Abu Mu'awiyah narrated to us, from Hisham ibn 'Urwah, from Wahb ibn Kaysan, from 'Ubayd ibn 'Umayr, he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "A people will certainly accompany the Dajjal, saying: 'We are indeed accompanying him, and we indeed know that he is a liar, but we are only accompanying him so that we may eat from his food and graze from his trees.' And when the anger of Allah descends, it will descend upon all of them."
