The Messenger of Allah ﷺ said: ʿThe Dajjal will emerge from a land in the east called Khurasan and he will be followed by peoples whose faces are like hammered shields.ʿ (Using translation from Aḥmad 12)
حَدَّثَنَا رَسُولُ اللَّهِ ﷺ «أَنَّ الدَّجَّالَ يَخْرُجُ مِنْ أَرْضٍ بِالْمَشْرِقِ يُقَالُ لَهَا خُرَاسَانُ يَتْبَعُهُ أَقْوَامٌ كَأَنَّ وُجُوهَهُمُ الْمَجَانُّ الْمُطْرَقَةُ»
