Ad-Dajjal was mentioned in the presence of the Prophet. The Prophet ﷺ 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."  

ذُكِرَ الدَّجَّالُ عِنْدَ النَّبِيِّ ﷺ فَقَالَ إِنَّ اللَّهَ لاَ يَخْفَى عَلَيْكُمْ إِنَّ اللَّهَ لَيْسَ بِأَعْوَرَ وَأَشَارَ بِيَدِهِ إِلَى عَيْنِهِ وَإِنَّ الْمَسِيحَ الدَّجَّالَ أَعْوَرُ الْعَيْنِ الْيُمْنَى كَأَنَّ عَيْنَهُ عِنَبَةٌ طَافِيَةٌ  

The Prophet ﷺ said, "Allah did not send any prophet but that he warned his nation of the one-eyed liar (Ad-Dajjal). He is one-eyed while your Lord is not one-eyed, The word 'Kafir' (unbeliever) is written between his two eyes."  

عَنِ النَّبِيِّ ﷺ قَالَ مَا بَعَثَ اللَّهُ مِنْ نَبِيٍّ إِلاَّ أَنْذَرَ قَوْمَهُ الأَعْوَرَ الْكَذَّابَ إِنَّهُ أَعْوَرُ وَإِنَّ رَبَّكُمْ لَيْسَ بِأَعْوَرَ مَكْتُوبٌ بَيْنَ عَيْنَيْهِ كَافِرٌ
