Musnad Ahmad 1034:64

Wahb ibn Jarir narrated to us, my father narrated to us, he said: I heard al-A’mash, from Abu Wa’il, from Hudhayfah, who said: The Dajjal was mentioned in the presence of the Messenger of Allah, may Allah bless him and grant him peace, and he said: "Indeed, the trial of some of you is more fearful to me than the trial of the Dajjal. No one will be saved from what is before it except that he will be saved from it. And no trial has been created since the world began, small or large, but that it is prepared for the trial of the Dajjal."
