Narrated Anas:

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."

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، أَخْبَرَنَا قَتَادَةُ، قَالَ سَمِعْتُ أَنَسًا ـ رضى الله عنه ـ عَنِ النَّبِيِّ ﷺ قَالَ " مَا بَعَثَ اللَّهُ مِنْ نَبِيٍّ إِلاَّ أَنْذَرَ قَوْمَهُ الأَعْوَرَ الْكَذَّابَ، إِنَّهُ أَعْوَرُ، وَإِنَّ رَبَّكُمْ لَيْسَ بِأَعْوَرَ، مَكْتُوبٌ بَيْنَ عَيْنَيْهِ كَافِرٌ ".
