Musnad Ahmad 11:3

Muhammad ibn Ja‘far narrated to us, Shu‘bah narrated to us, from Khalid, from ‘Abdullah ibn Shaqiq, from ‘Abdullah ibn Suraqah, from Abu ‘Ubaydah ibn al-Jarrah, from the Prophet (peace and blessings of Allah be upon him), that he mentioned the Dajjal and described him with a description that I do not memorize. They said: "O Messenger of Allah, will our hearts be on that day as they are today?" He said: "Or better."
