Musnad Abu Ya'la al-Mawsili 78:5

Zuhayr narrated to us, Ahmad ibn Ishaq narrated to us, Abd al-Aziz narrated to us, Ayyub narrated to us, from Humayd ibn Hilal, from a group among whom were Abu al-Dahma’ and Abu Qatadah, who said: We used to pass by Hisham and go to Imran ibn Husayn. He said one day: "You pass by me to men who were not more intimate with the Messenger of Allah (may Allah bless him and grant him peace) than I, nor more knowledgeable of his hadith than I. I heard the Messenger of Allah (may Allah bless him and grant him peace) say: 'Between the creation of Adam and the establishment of the Hour, there is no creation greater than the Dajjal.'"
