Musnad Ahmad 32:64

'Amr ibn al-Haytham narrated to us, Shu'bah narrated to us, from Qatadah, from Anas ibn Malik, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "No prophet was sent but that he warned his nation about the one-eyed liar. Behold, he is one-eyed, and your Lord is not one-eyed. Written between his eyes is: 'Kafir' (disbeliever)."
