عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ حَدَّثَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ حَدِيثًا طَوِيلًا عَنِ الدَّجَّالِ فَقَالَ فِيمَا يُحَدِّثُنَا قَالَ ”تَأْتِي الدَّجَّالُ وَهُوَ مُحَرَّمٌ عَلَيْهِ أَنْ يَدْخُلَ نِقَابَ الْمَدِينَةِ فَيَخْرُجُ إِلَيْهِ رَجُلٌ يَوْمَئِذٍ وَهُوَ خَيْرُ النَّاسِ أَوْ مِنْ خَيْرِهِمْ فَيَقُولُ أَشْهَدُ أَنَّكَ الدَّجَّالُ الَّذِي حَدَّثَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ حَدِيثَهُ فَيَقُولُ الدَّجَّالُ أَرَأَيْتُمْ إِنْ قَتَلْتُ هَذَا ثُمَّ أَحْيَيْتُهُ أَتَشُكُّونَ فِي الْأَمْرِ فَيَقُولُونَ لَا فَيَقْتُلُهُ ثُمَّ يُحْيِيهِ فَيَقُولُ حِينَ يَحْيَا وَاللَّهِ مَا كُنْتُ قَطُّ أَشَدَّ بَصِيرَةً فِيكَ مِنِّي الْآنَ قَالَ فَيُرِيدُ قَتْلَهُ الثَّانِيَةَ فَلَا يُسَلَّطُ عَلَيْهِ“
It is narrated from Sayyiduna Abu Sa'id Khudri, may Allah be pleased with him, who says: The Messenger of Allah, peace and blessings be upon him, narrated to us a lengthy hadith about the Dajjal, in which he, peace and blessings be upon him, also said: When the Dajjal comes, it will be forbidden for him to enter the paths of Madinah Munawwarah. The best man of that time will go to the Dajjal and say to him: I bear witness that you are indeed the Dajjal about whom the Messenger of Allah, peace and blessings be upon him, warned us. Hearing this, the Dajjal will say to the people: What do you think, if I kill this man and then bring him back to life, will you still have any doubt about me? They will say: No. So the Dajjal will kill that man and then bring him back to life. After being brought back to life, the man will say: By Allah! I now have more insight about your being the Dajjal than I had before. Then the Dajjal will try to kill him again, but he will not be able to kill him.
