وَلَقَدْ أَرْسَلْنَا مِن قَبْلِكَ رُسُلًا إِلَىٰ قَوْمِهِمْ فَجَآءُوهُم بِٱلْبَيِّنَٰتِ فَٱنتَقَمْنَا مِنَ ٱلَّذِينَ أَجْرَمُوا۟ ۖ وَكَانَ حَقًّا عَلَيْنَا نَصْرُ ٱلْمُؤْمِنِينَ
Verily We sent before thee (Muhammad) messengers to their own folk. Then we took vengeance upon those who were guilty (in regard to them). To help believers is ever incumbent upon Us.

Chapter: Reciting Talbiya on entering a valley
Narrated Mujahid:
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. ' "
