Narrated Ibn 'Umar (ra) :
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ ، حَدَّثَنَا وُهَيْبٌ ، حَدَّثَنَا أَيُّوبُ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ، أُرَاهُ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " أَعْوَرُ عَيْنِ الْيُمْنَى، كَأَنَّهَا عِنَبَةٌ طَافِيَةٌ " .
The Prophet (ﷺ) said (about Ad-Dajjal) that he is one eyed, his right eye is as if a protruding out grape."
