The Messenger of Allah ﷺ mentioned the Dajjal (Antichrist) saying: If he comes forth while I am among you I shall be the one who will dispute with him on your behalf, but if he comes forth when I am not among you, a man must dispute on his own behalf, and Allah will take my place in looking after every Muslim. Those of you who live up to his time should recite over him the opening verses of Surat al – Kahf, for they are your protection from his trial. We asked: How long will he remain on the earth ? He replied : Forty days, one like a year, one like a month, one like a week, and rest of his days like yours. We asked : Messenger of Allah, will one day’s prayer suffice us in this day which will be like a year ? He replied : No, you must make an estimate of its extent. Then Jesus son of Marry will descend at the white minaret to the east of Damascus. He will then catch him up at the date of Ludd and kill him.  

ذَكَرَ رَسُولُ اللَّهِ ﷺ الدَّجَّالَ فَقَالَ إِنْ يَخْرُجْ وَأَنَا فِيكُمْ فَأَنَا حَجِيجُهُ دُونَكُمْ وَإِنْ يَخْرُجْ وَلَسْتُ فِيكُمْ فَامْرُؤٌ حَجِيجُ نَفْسِهِ وَاللَّهُ خَلِيفَتِي عَلَى كُلِّ مُسْلِمٍ فَمَنْ أَدْرَكَهُ مِنْكُمْ فَلْيَقْرَأْ عَلَيْهِ فَوَاتِحَ سُورَةِ الْكَهْفِ فَإِنَّهَا جِوَارُكُمْ مِنْ فِتْنَتِهِ قُلْنَا وَمَا لُبْثُهُ فِي الأَرْضِ قَالَ أَرْبَعُونَ يَوْمًا يَوْمٌ كَسَنَةٍ وَيَوْمٌ كَشَهْرٍ وَيَوْمٌ كَجُمُعَةٍ وَسَائِرُ أَيَّامِهِ كَأَيَّامِكُمْ فَقُلْنَا يَا رَسُولَ اللَّهِ هَذَا الْيَوْمُ الَّذِي كَسَنَةٍ أَتَكْفِينَا فِيهِ صَلاَةُ يَوْمٍ وَلَيْلَةٍ قَالَ لاَ اقْدُرُوا لَهُ قَدْرَهُ ثُمَّ يَنْزِلُ عِيسَى ابْنُ مَرْيَمَ عِنْدَ الْمَنَارَةِ الْبَيْضَاءِ شَرْقِيَّ دِمَشْقَ فَيُدْرِكُهُ عِنْدَ بَابِ لُدٍّ فَيَقْتُلُهُ  

[Machine] The Messenger of Allah ﷺ mentioned the Dajjal and said: "If he appears while I am among you, then I will be the one who will refute him. But if he appears and I am not among you, then every person must refute him on his own, and Allah is my successor over every Muslim. Indeed, his one eye is covered like a blind man's eye, resembling the eye of Abd al-Uzza bin Qatan al-Khazai. Indeed, between his two eyes, "disbeliever" is written, and every Muslim can read it. So whoever among you meets him, let him recite the Opening Chapter of the Cave and he will come out between Sham and Iraq, causing destruction to the right and to the left. O servants of Allah, be firm" He said this three times. They asked, "O Messenger of Allah, how long will he stay on earth?" He said, "Forty days, one day like a year, one day like a month, one day like a week, and the rest of his days like your days." They said, "O Messenger of Allah, how should we perform prayers on that day? Should we calculate [its timing] as one day or take an approximation?" He said, "You should calculate [its timing]."  

أَنَّ رَسُولَ اللَّهِ ﷺ ذَكَرَ الدَّجَّالَ فَقَالَ «إِنْ يَخْرُجْ وَأَنَا فِيكُمْ فَأَنَا حَجِيجُهُ وَإِنْ يَخْرُجْ وَلَسْتُ فِيكُمْ فَكُلُّ امْرِئٍ حَجِيجُ نَفْسِهِ وَاللَّهُ خَلِيفَتِي عَلَى كُلِّ مُسْلِمٍ أَلَا وَإِنَّهُ مَطْمُوسُ الْعَيْنِ كَأَنَّهَا عَيْنُ عَبْدِ الْعُزَّى بْنِ قَطَنٍ الْخُزَاعِيِّ أَلَا فَإِنَّهُ مَكْتُوبٌ بَيْنَ عَيْنَيْهِ كَافِرٌ يَقْرَأُ كُلُّ مُسْلِمٍ فَمَنْ لَقِيَهُ مِنْكُمْ فَلْيَقْرَأْ بِفَاتِحَةِ الْكَهْفِ يَخْرُجُ مِنْ بَيْنِ الشَّامِ وَالْعِرَاقِ فَعَاثَ يَمِينًا وَعَاثَ شِمَالًا يَا عِبَادَ اللَّهِ اثْبُتُوا» ثَلَاثًا فَقِيلَ يَا رَسُولَ اللَّهِ فَمَا مُكْثُهُ فِي الْأَرْضِ؟ قَالَ أَرْبَعُونَ يَوْمًا يَوْمٌ كَالسَّنَةِ وَيَوْمٌ كَالشَّهْرِ وَيَوْمٌ كَالْجُمُعَةِ وَسَائِرُ أَيَّامِهِ كَأَيَّامِكُمْ قَالُوا يَا رَسُولَ اللَّهِ فَكَيْفَ نَصْنَعُ بِالصَّلَاةِ يَوْمَئِذٍ صَلَاةُ يَوْمٍ أَوْ نَقْدُرُ؟ قَالَ «بَلْ تَقْدُرُوا»
