Narrated Mujahid:
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى ، قَالَ حَدَّثَنِي ابْنُ أَبِي عَدِيٍّ ، عَنِ ابْنِ عَوْنٍ ، عَنْ مُجَاهِدٍ ، قَالَ كُنَّا عِنْدَ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ فَذَكَرُوا الدَّجَّالَ أَنَّهُ قَالَ " مَكْتُوبٌ بَيْنَ عَيْنَيْهِ كَافِرٌ ". فَقَالَ ابْنُ عَبَّاسٍ لَمْ أَسْمَعْهُ وَلَكِنَّهُ قَالَ " أَمَّا مُوسَى كَأَنِّي أَنْظُرُ إِلَيْهِ إِذِ انْحَدَرَ فِي الْوَادِي يُلَبِّي " .
I was in the company of Ibn `Abbas and the people talked about Ad-Dajjal and said, "Ad-Dajjal will come with the word Kafir (non-believer) written in between his eyes." On that Ibn `Abbas said, "I have not heard this from the Prophet (ﷺ) but I heard him saying, 'As if I saw Moses just now entering the valley reciting Talbyia. ' "
