Musnad Ahmad 8:88

Yazid ibn Harun narrated to us, Muhammad ibn Ishaq informed us, from Dawud ibn Amir ibn Sa'd ibn Malik, from his father, from his grandfather, who said: The Messenger of Allah, peace and blessings of Allah be upon him, said: "There was no prophet except that he described the Dajjal to his nation, and I shall describe him with a description that no one before me has described: He is one-eyed, and Allah, the Almighty and Majestic, is not one-eyed."
