Musnad Abu Ya'la al-Mawsili 154:194

Ishaq ibn Abi Isra'il narrated to us, Abu Umayyah ibn Ya'la narrated to us, he said: Nafi' narrated to me, from Ibn Umar, he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, Allah is not one-eyed. The False Messiah (al-Masih al-Dajjal) is one-eyed in his right eye, as if it were a floating grape."
