Musnad Ahmad 1012:98

Haywah ibn Shurayh and Yazid ibn Abd Rabbih narrated to us, they said: Baqiyyah narrated to us, Buhayr ibn Sa’d narrated to me, from Khalid ibn Ma’dan, from ‘Amr ibn al-Aswad, from Junadah ibn Abi Umayyah, that he narrated to them, from ‘Ubadah ibn al-Samit, that he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "I have indeed told you about the Dajjal until I feared that you would not understand. The Messiah Dajjal is a short man, bow-legged, curly-haired, one-eyed, with an obliterated eye that is neither protruding nor sunken. If he confuses you—Yazid said: [If he says] 'Your Lord'—then know that your Lord is not one-eyed, and that you will not see your Lord until you die." Yazid said: "[You will not] see your Lord until you die."
