عَنْ أَنَسٍ، رضى الله عنه قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم: مَا بُعِثَ نَبِيٌّ إِلاَّ أَنْذَرَ أُمَّتَهُ الأَعْوَرَ الْكَذَّابَ، أَلاَ إِنَّهُ أَعْوَرُ، وَإِنَّ رَبَّكُمْ لَيْسَ بِأَعْوَرَ، وَإِنَّ بَيْنَ عَيْنَيْهِ مَكْتُوبٌ كَافِرٌ.
It is narrated by Hazrat Abu Anasra that, “The Prophetsa said, ‘No prophet was sent but that he warned his followers against the one-eyed liar (Ad-Dajjal). Beware! He is blind in one eye, and your Lord is not so, and there will be written between his eyes ‘kafir’ (i.e., disbeliever).”
(Sahih al-Bukhari, Kitan al-ftan, Bab qawlillahi ‘azza wa jalla: ‘wa laqad arsalna nuhan ila qawmihi’, Hadith 3338)
