Book 54 · Hadith 7182
وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا عَفَّانُ، حَدَّثَنَا عَبْدُ الْوَارِثِ، عَنْ شُعَيْبِ بْنِ الْحَبْحَابِ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الدَّجَّالُ مَمْسُوحُ الْعَيْنِ مَكْتُوبٌ بَيْنَ عَيْنَيْهِ كَافِرٌ " . ثُمَّ تَهَجَّاهَا ك ف ر " يَقْرَؤُهُ كُلُّ مُسْلِمٍ " .
Anas b. Malik reported that Allah's Messenger (ﷺ) said: Dajjal is blind of one eye and there is written between his eyes the word" Kafir". He then spelled the word as k. f. r., which every Muslim would be able to read.
