Sahih Muslim 2943a
Anas b. Malik reported that Messenger of Allah ﷺ said: There will be no land which would not be covered by the Dajjal but Mecca and Medina, and there would no passage out of the passages leading to them which would not be guarded by angels arranged in rows. Then he (the Dajjal) would appear in a barren place adjacent to Medina and it would rock three times that every unbeliever and hypocrite would get out of it towards him.
حَدَّثَنِي عَلِيُّ بْنُ حُجْرٍ السَّعْدِيُّ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، حَدَّثَنِي أَبُو عَمْرٍو، - يَعْنِي الأَوْزَاعِيَّ - عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ، حَدَّثَنِي أَنَسُ بْنُ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " لَيْسَ مِنْ بَلَدٍ إِلاَّ سَيَطَؤُهُ الدَّجَّالُ إِلاَّ مَكَّةَ وَالْمَدِينَةَ وَلَيْسَ نَقْبٌ مِنْ أَنْقَابِهَا إِلاَّ عَلَيْهِ الْمَلاَئِكَةُ صَافِّينَ تَحْرُسُهَا فَيَنْزِلُ بِالسَّبَخَةِ فَتَرْجُفُ الْمَدِينَةُ ثَلاَثَ رَجَفَاتٍ يَخْرُجُ إِلَيْهِ مِنْهَا كُلُّ كَافِرٍ وَمُنَافِقٍ " .
