Musnad Ahmad 27:499

Hammad narrated to us, he said: Ubaydullah informed us, and Muhammad ibn Bishr said: Ubaydullah narrated to us, from Nafi’, from Ibn Umar, that the Messenger of Allah (may Allah bless him and grant him peace) mentioned the Messiah—Ibn Bishr said in his hadith: and he mentioned the Dajjal—among the people, and he said: "Indeed, Allah, Blessed and Exalted is He, is not one-eyed. Behold, the Messiah Dajjal is blind in his right eye, as if his eye is a floating grape."
