Sahih Bukhari Volume 9, Book 97, Hadith 7409

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا جُوَيْرِيَةُ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ، قَالَ ذُكِرَ الدَّجَّالُ عِنْدَ النَّبِيِّ صلى الله عليه وسلم فَقَالَ ‏"‏ إِنَّ اللَّهَ لاَ يَخْفَى عَلَيْكُمْ، إِنَّ اللَّهَ لَيْسَ بِأَعْوَرَ ـ وَأَشَارَ بِيَدِهِ إِلَى عَيْنِهِ ـ وَإِنَّ الْمَسِيحَ الدَّجَّالَ أَعْوَرُ الْعَيْنِ الْيُمْنَى كَأَنَّ عَيْنَهُ عِنَبَةٌ طَافِيَةٌ ‏"‏‏

Narrated By 'Abdullah : Ad-Dajjal was mentioned in the presence of the Prophet. The Prophet said, "Allah is not hidden from you; He is not one-eyed," and pointed with his hand towards his eye, adding, "While Al-Masih Ad-Dajjal is blind in the right eye and his eye looks like a protruding grape."
