The Prophet ﷺ said, "The terror caused by Al-Masih Ad-Dajjal will not enter Medina and at that time Medina will have seven gates and there will be two angels at each gate guarding them."  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَدْخُلُ الْمَدِينَةَ رُعْبُ الْمَسِيحِ الدَّجَّالِ لَهَا يَوْمَئِذٍ سَبْعَةُ أَبْوَابٍ عَلَى كُلِّ باب مَلَكَانِ  

Messenger of Allah ﷺ said, "There are angels guarding the entrances (or roads) of Medina, neither plague nor Ad-Dajjal will be able to enter it."  

قَالَ رَسُولُ اللَّهِ ﷺ عَلَى أَنْقَابِ الْمَدِينَةِ مَلاَئِكَةٌ لاَ يَدْخُلُهَا الطَّاعُونُ وَلاَ الدَّجَّالُ  

The Prophet ﷺ said, "There will be no town which Ad-Dajjal will not enter except Mecca and Medina, and there will be no entrance (road) (of both Mecca and Medina) but the angels will be standing in rows guarding it against him, and then Medina will shake with its inhabitants thrice (i.e. three earthquakes will take place) and Allah will expel all the non-believers and the hypocrites from it."  

عَنِ النَّبِيِّ ﷺ قَالَ لَيْسَ مِنْ بَلَدٍ إِلاَّ سَيَطَؤُهُ الدَّجَّالُ إِلاَّ مَكَّةَ وَالْمَدِينَةَ لَيْسَ لَهُ مِنْ نِقَابِهَا نَقْبٌ إِلاَّ عَلَيْهِ الْمَلاَئِكَةُ صَافِّينَ يَحْرُسُونَهَا ثُمَّ تَرْجُفُ الْمَدِينَةُ بِأَهْلِهَا ثَلاَثَ رَجَفَاتٍ فَيُخْرِجُ اللَّهُ كُلَّ كَافِرٍ وَمُنَافِقٍ  

Messenger of Allah ﷺ told us a long narrative about Ad-Dajjal, and among the many things he mentioned, was his saying, "Ad-Dajjal will come and it will be forbidden for him to pass through the entrances of Medina. He will land in some of the salty barren areas (outside) Medina; on that day the best man or one of the best men will come up to him and say, 'I testify that you are the same Dajjal whose description was given to us by Messenger of Allah ﷺ .' Ad-Dajjal will say to the people, 'If I kill this man and bring him back to life again, will you doubt my claim?' They will say, 'No.' Then Ad-Dajjal will kill that man and bring him back to life. That man will say, 'Now I know your reality better than before.' Ad-Dajjal will say, 'I want to kill him but I cannot.' "  

أَنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ ؓ قَالَ حَدَّثَنَا رَسُولُ اللَّهِ ﷺ حَدِيثًا طَوِيلاً عَنِ الدَّجَّالِ فَكَانَ فِيمَا حَدَّثَنَا بِهِ أَنْ قَالَ يَأْتِي الدَّجَّالُ وَهُوَ مُحَرَّمٌ عَلَيْهِ أَنْ يَدْخُلَ نِقَابَ الْمَدِينَةِ بَعْضَ السِّبَاخِ الَّتِي بِالْمَدِينَةِ فَيَخْرُجُ إِلَيْهِ يَوْمَئِذٍ رَجُلٌ هُوَ خَيْرُ النَّاسِ أَوْ مِنْ خَيْرِ النَّاسِ فَيَقُولُ أَشْهَدُ أَنَّكَ الدَّجَّالُ الَّذِي حَدَّثَنَا عَنْكَ رَسُولُ اللَّهِ ﷺ حَدِيثَهُ فَيَقُولُ الدَّجَّالُ أَرَأَيْتَ إِنْ قَتَلْتُ هَذَا ثُمَّ أَحْيَيْتُهُ هَلْ تَشُكُّونَ فِي الأَمْرِ فَيَقُولُونَ لاَ فَيَقْتُلُهُ ثُمَّ يُحْيِيهِ فَيَقُولُ حِينَ يُحْيِيهِ وَاللَّهِ مَا كُنْتُ قَطُّ أَشَدَّ بَصِيرَةً مِنِّي الْيَوْمَ فَيَقُولُ الدَّجَّالُ أَقْتُلُهُ فَلاَ أُسَلَّطُ عَلَيْهِ
