In his Sahih, Muslim recorded that Abu Hurayrah related to the Messenger of Allah that he said,

«لَا تَقُومُ السَّاعَةُ حَتَّى يَنْزِلَ الرُّومُ بِالْأَعْمَاقِ أَوَ بِدَابِقَ، فَيَخْرُجُ إِلَيْهِمُ جَيْشٌ مِنَ الْمَدِينَةِ مِنْ خِيَارِ أَهْلِ الْأَرْضِ يَوْمَئِذٍ، فَإِذَا تَصَافُّوا، قَالَتِ الرُّومُ: خَلُّوا بَيْنَنَا وَبَيْنَ الَّذِينَ سَبَوْا مِنَّا نُقَاتِلْهُمْ، فَيَقُولُ الْمُسْلِمُونَ: لَا وَاللهِ، لَا نُخَلِّي بَيْنَكُمْ وَبَيْنَ إِخْوَانِنَا، فَيُقَاتِلُونَهُمْ، (فَيَنْهَزِمُ) ثُلُثٌ لَا يَتُوبُ اللهُ عَلَيْهِمْ أَبَدًا، وَيُقْتَلُ ثُلُثُهُ أَفْضَلُ الشُّهَدَاءِ عِنْدَ اللهِ، وَيَفْتَتحُ الثَّلُثُ لَا يُفْتَنُونَ أَبَدًا، فَيَفْتَتِحُونَ قُسْطُنْطِينِيَّةَ، فَبَيْنَمَا هُمْ يَقْسِمُونَ الْغَنَائِمَ قَدْ عَلَّقُوا سُيُوفَهُمْ بِالزَّيْتُونِ، إِذْ صَاحَ فِيهِمُ الشَّيْطَانُ: إِنَّ الْمَسِيحَ قَدْ خَلَفَكُمْ فِي أَهْلِيكُمْ، فَيَخْرُجُونَ، وَذَلِكَ بَاطِلٌ، فَإِذَا جَاءُوا الشَّامَ خَرَجَ، فَبَيْنَمَا هُمْ يُعِدُّونَ لِلْقِتَالِ يُسَوُّونَ الصُّفُوفَ، إِذْ أُقِيَمتِ الصَّلَاةُ فَيَنْزِلُ عِيسَى ابْنُ مَرْيَمَ، فَأَمَّهُمْ، فَإِذَا رَآهُ عَدُوُّ اللهِ، ذَابَ كَمَا يَذُوبُ الْمِلْحُ فِي الْمَاءِ، فَلَوْ تَرَكَهُ لَانْذَابَ حَتَّى يَهْلِكَ، وَلكِنْ يَقْتُلُهُ اللهُ بِيَدِهِ، فَيُرِيهِمْ دَمَهُ فِي حَرْبَتِه»

(The (Last) Hour will not start until the Romans occupy Al-A`maq or Dabiq. An army, comprised of the best of the people of the earth then, will come from Al-Madinah and challenge them. When they camp face to face, the Romans will say, `Let us fight those who captured some of us.' The Muslims will say, `Nay! By Allah, we will never let you get to our brothers.' They will fight them. A third of the (Muslim) army will flee in defeat, and those are the ones whom Allah will never forgive. Another third will be killed, and those are the best martyrs before Allah. The last third will be victorious, and this third will never be stricken with Fitnah, and they will capture Constantinople (Istanbul). While they are dividing war booty, after hanging their swords on olive trees, Shaytan will shout among them, saying, `Al-Masih (Ad-Dajjal) has cornered your people'. They will leave to meet Ad-Dajjal in Ash-Sham. This will be a false warning, and when they reach Ash-Sham, Ad-Dajjal will then appear. When the Muslims are arranging their lines for battle and the prayer is called for, `Isa, son of Maryam, will descend and lead them in prayer. When the enemy of Allah (the False Messiah) sees him, he will dissolve just as salt dissolves in water, and if any of him were left, he would continue dissolving until he died. Allah will kill him with the hand of `Isa and will show the Muslims his blood on his spear.) Muslim recorded that `Abdullah bin `Amr said that the Messenger of Allah said,

«لَتُقَاتِلُنَّ الْيَهُودَ فَلَتَقْتُلُنَّهُمْ، حَتَى يَقُولَ الْحَجَرُ: يَامُسْلِمُ هَذَا يَهُودِيٌّ فَتَعَال فَاقْتُلْه»

(You will fight the Jews and will kill them, until the stone will say, `O Muslim! There is a Jew here, so come and kill him.') Muslim recorded that Abu Hurayrah said that the Messenger of Allah said,

«لَا تَقُومُ السَّاعَةُ حَتَّى يُقَاتِلَ الْمُسْلِمُونَ الْيَهُودَ، فَيَقْتُلُهُمُ الْمُسْلِمُونَ حَتَّى يَخْتَبِىءَ الْيَهُودِيُّ مِنْ وَرَاءِ الْحَجَرِ وَالشَّجَرِ، فَيَقُولُ الْحَجَرُ وَالشَّجَرُ: يَامُسْلِمُ يَاعَبْدَاللهِ هَذَا يَهُودِيٌّ خَلْفِي فَتَعَالَ فَاقْتُلْهُ إِلَّا الْغَرْقَدَ فَإِنَّهُ مِنْ شَجَرِ الْيَهُود»

(The Hour will not start, until after the Muslims fight the Jews and the Muslims kill them. The Jew will hide behind a stone or tree, and the tree will say, `O Muslim! O servant of Allah! This is a Jew behind me, come and kill him.' Except Al-Gharqad, for it is a tree of the Jews.) Muslim bin Al-Hajjaj recorded in his Sahih that An-Nawwas bin Sam`an said, "The Messenger of Allah , mentioned Ad-Dajjal one day and kept belittling him (because being blind, yet claiming to be Allah) and speaking in grave terms about him until we thought that he was hiding in gardens of date-trees (in Al-Madinah). When we went by the Messenger, he sensed this anxiety in us and said,

«مَا شَأْنُكُمْ؟»

(What is the matter with you) We said, `O Messenger of Allah! Earlier, you mentioned Ad-Dajjal and while belittling him you spoke gravely about him until we thought that he was hiding in gardens of date-trees (of Al-Madinah).' He said,

«غَيْرُ الدَّجَّالِ أَخْوَفُنِي عَلَيكُمْ، إِنْ يخْرُجْ وَأَنَا فِيكُمْ فَأَنَا حَجِيجُهُ دُونَكُمْ، وَإِنْ يَخْرُجْ وَلَسْتُ فِيكُمْ فَامْرُؤٌ حَجِيجُ نَفْسِهِ، واللهُ خَلِيفَتِي عَلى كُلِّ مُسْلمٍ. إِنَّهُ شَابٌّ قَطَطٌ، عَينُهُ طافِيةٌ كَأَنِّي أُشَبِّهُهُ بِعَبْدِالعُزَّى بْنِ قَطَنٍ، مَنْ أَدْرَكَهُ مِنْكُمْ فَلْيَقْرَأ عَلَيْهِ فَوَاتِحَ سُورَةِ الْكَهْفِ، إِنَّه خَارِجٌ مِنْ خَلَّةٍ بَيْنَ الشَّامِ والعِرَاقِ، فَعَاثَ يَمِينًا وَعَاثَ شِمَالًا، يَاعِبَادَ اللهِ فَاثْبُتوا»

(I fear other than Ad-Dajjal for you! If he appears while I am still among you, I will be his adversary on your behalf. If he appears while I am not among you, each one will depend on himself and Allah will be the Helper of every Muslim after me. He is young, with very curly hair and his eye is smashed. I thought that he looked like `Abdul-`Uzza bin Qatan. Whoever lives long and meets Ad-Dajjal, then let him recite the beginnings of Surat Al-Kahf. He will appear on a pass between Ash-Sham (Syria) and Al-`Iraq. He will wreak havoc to the right and left. O Servants of Allah! Hold fast.) We said, `O Messenger of Allah! How long will he stay on earth' He said,

«أَرْبَعُونَ يَوْمًا، يَومٌ كَسَنَةٍ، وَيَوْمٌ كَشَهْرٍ، وَيَوْمٌ كَجُمُعَةٍ، وَسَائِرُ أَيَّامِهِ كَأَيَّامِكُم»

(Forty days: One day as long as a year, one day as long as a month and one day as long as a week. The rest of his days will be as long as one of your ordinary days.) We said, `O Messenger of Allah! As for the day that is like a year, will the prayers of one day suffice for it' He said,

«لَا، اقْدُرُوا لَهُ قَدْرَه»

(No. Count for its due measure.) We said, `O Messenger of Allah, how will his speed be on earth' He said,

«كَالْغَيْثِ اسْتَدْبَرَتْهُ الرِّيحُ فَيَأْتِي عَلى قَوْمٍ فَيَدْعُوهُمْ فَيُؤْمِنُون بِهِ، وَيَسْتَجِيبُونَ لَهُ، فَيَأْمُرُ السَّمَاءَ فَتُمْطِرُ، وَالأَرْضَ فَتُنْبِتُ، فَتَرُوحُ عَلَيْهِمْ سَارِحَتُهُمْ أَطْوَلَ مَا كَانَتْ ذُرًى، وَأَسْبَغَهُ ضُرُوعًا، وَأَمَدَّهُ خَوَاصِرَ، ثُمَّ يَأْتِي الْقَوْمَ فَيَدْعُوهُمْ فَيَرُدُّونَ عَلَيْهِ قَوْلَهُ، فَيَنْصَرِفُ عَنْهُمْ فَيُصْبِحُونَ مُمْحِلِينَ لَيْسَ بِأَيْدِيهِمْ شَيْءٌ مِنْ أَمْوَالِهِمْ وَيَمُرُّ بِالْخَرِبَةِ فَيَقُولُ لَهَا: أَخْرِجِي كُنُوزَكِ، فَتَتْبَعُهُ كُنُوزُهَا كَيعَاسِيبِ النَّحْلِ، ثُمَّ يَدْعُو رَجُلًا مُمْتَلِئًا شَبَابًا فَيَضْرِبُهُ بِالسَّيْفِ، فَيَقْطَعُهُ جِزْلَتَيْنِ رَمْيَةَ الْغَرَضِ، ثُمَّ يَدْعُوهُ، فَيُقْبِلُ وَيَتَهَلَّلُ وَجْهُهُ وَيَضْحَكُ، فَبَيْنَما هُوَ كَذَلِكَ إِذْ بَعَثَ اللهُ الْمَسِيَح ابْنَ مَرْيَمَ عَلَيْهِ السَّلَامُ، فَيَنْزِلُ عِنْدَ المَنَارَةِ البَيْضَاءِ شَرْقِيَّ دِمَشْقَ بَيْنَ مَهْرُودَتَيْنِ، وَاضِعًا كَفَّيْهِ عَلَى أَجْنِحَةِ مَلَكَيْنِ، إِذَا طَأْطَأَ رَأْسَهُ قَطَرَ،وَإذَا رَفَعَهُ تَحَدَّرَ مِنْهُ جُمَانٌ كَاللُّؤْلُؤِ، وَلَا يَحِلُّ لِكَافِرٍ يَجِدُ رِيحَ نَفَسِهِ إِلَّا مَاتَ، وَنَفَسُهُ يَنْتَهِي حَيْثُ يَنْتَهِي طَرَفُهُ، فَيَطْلُبُهُ حَتَّى يُدْرِكَهُ بِبَابِ لُدَ، فَيَقْتُلُهُ، ثُمَّ يَأْتِي عِيسَى عَلَيْهِ السَّلَامُ قَوْمًا قَدْ عَصَمَهُمُ اللهُ مِنْهُ، فَيَمْسَحُ عَنْ وُجُوهِهِمْ، وَيُحَدِّثُهُمْ بدَرَجَاتِهِمْ فِي الْجَنَّةِ، فَبَيْنَمَا هُوَ كَذَلِكَ إِذْ أَوْحَى اللهُ عَزَّ وَجَلَّ إِلَى عِيسَى: إِنِّي قَدْ أَخْرَجْتُ عِبَادًا لِي لَا يَدَانِ لِأَحَدٍ بِقِتَالِهِمْ، فَحَرِّزْ عِبَادِي إِلَى الطُّورِ، ويَبْعَثُ اللهُ يَأْجُوجَ وَمَأْجُوجَ وَهُمْ مِنْ كُلِّ حَدَبٍ يَنْسِلُونَ، فَيَمُرُّ أَوَّلُهُمْ عَلَى بُحَيْرَةِ طَبَرِيَّةَ فَيَشْرَبُونَ مَا فِيهَا، وَيَمُرُّ آخِرُهُمْ فَيقُولُونَ: لَقَدْ كَانَ بِهذِهِ مَرَّةً مَاءٌ، ويُحْصَرُ نَبِيُّ اللهِ عِيسَى وَأَصْحَابُهُ، حَتَّى يَكُونَ رَأْسُ الثَّورِ لِأَحَدِهِمْ خَيْرٌ مِنْ مِائَةِ دِينَارٍ لِأَحَدِكُمُ الْيَوْمَ، فَيَرْغَبُ نَبِيُّ اللهِ عِيسَى وَأَصْحَابُهُ، فَيُرسِلُ اللهُ عَلَيْهِمُ النَّغَفَ فِي رِقَابِهِمْ، فَيُصْبِحُونَ فَرْسَى كَمَوْتِ نَفْسٍ وَاحِدَةٍ، ثُمَّ يَهْبِطُ نَبِيُّ اللهِ عِيسَى وَأَصْحَابُهُ إِلَى الْأَرْضِ، فَلَا يَجِدُونَ فِي الْأَرْضِ مَوْضِعَ شِبْرٍ إِلَّا مَلَأَهُ زَهَمُهُمْ ونَتْنُهُمْ، فَيَرْغَبُ نَبِيُّ اللهِ عِيسَى وَأَصْحَابُهُ إِلَى اللهِ، فَيُرْسِلُ اللهُ، طَيْرًا كَأَعْنَاقِ الْبُخْتِ، فَتَحْمِلُهُمْ فَتَطْرَحُهُمْ حَيْثَ شَاءَ اللهُ، ثُمَّ يُرْسِلُ اللهُ مَطَرًا لَا يَكُنُّ مِنْهُ بَيْتُ مَدَرٍ، وَلَا وَبَرٍ، فَيَغْسِلُ الْأَرْضَ حَتَّى يَتْرُكَهَا كَالزَّلَفَةِ، ثُمَّ يُقَالُ لِلْأَرْضِ: أَخْرِجِي ثَمَرَكِ وَرُدِّي بَرَكَتَكِ، فَيَوْمَئِذٍ تَأْكُلُ الْعِصَابَةُ مِنَ الرُّمَّانَةِ، وَيَسْتَظِلُّونَ بِقِحْفِهَا، وَيُبَارِكُ اللهُ فِي الرِّسْلِ حَتَّى إِنَّ اللِّقْحَةَ مِنَ الْإِبِلِ لَتَكْفِي الفِئَامَ، (مِنَ النَّاسِ وَاللُّقْمَةَ مِنَ الْفَمِ لَتَكْفِي الْفَخِذَ مِنَ النَّاسِ)، فَبَيْنَما هُمْ كَذَلِكَ إِذْ بَعَثَ اللهُ رِيحًا طَيِّبَةً، فَتَأْخُذُهُمْ تَحْتَ آبَاطِهِمْ، فَتَقْبِضُ رُوحَ كُلِّ مُؤْمِنٍ وَكُلِّ مُسْلِمٍ، وَيَبْقَى شِرَارُ النَّاسِ يَتَهَارَجُونَ فِيهَا تَهَارُجَ الْحُمُرِ،فَعَلَيْهِمْ تَقُومُ السَّاعَة»

(Like the storm when driven by the wind. He will come to a people and will call them (to his worship), and they will believe in him and accept his call. He will order the sky and it will rain, the land and it will grow (vegetation). Their cattle will return to them with their hair the longest, their udders the fullest (with milk) and their stomachs the fattest. He will come to a different people and will call them (to his worship), and they will reject his call. He will then leave them. They will wake up in the morning destitute, missing all of their possessions. He will pass by a deserted land and will say to it, `Bring out your treasures', and its treasures will follow him just like swarms of bees. He will summon a man full of youth and will strike him with the sword once and will cut him into two pieces (and will separate between them like) the distance (between the hunter and) the game. He will call the dead man and he will come, and his face will radiant with pleasure and laughter. Afterwards (while all this is happening with Ad-Dajjal), Allah will send Al-Masih (`Isa), son of Maryam down. He will descend close to the white minaret to the east of Damascus. He will be wearing garments lightly colored with saffron and his hands will be placed on the wings of two angels. Whenever he lowers his head droplets fall. Whenever he raises his head, precious stones that look like pearls fall. No disbeliever can survive `Isa's breath, which reaches the distance of his sight. He will pursue Ad-Dajjal and will follow him to the doors of (the Palestinian city of) Ludd where he will kill him. A group of people who, by Allah's help, resisted and survived Ad-Dajjal, will pass by `Isa and he will anoint their faces and inform them about their grades in Paradise. Shortly afterwards, while this is happening with `Isa, Allah will reveal to him, `I raised a people of My creation that no one can fight. Therefore, gather My servants to At-Tur (the mountain of Musa in Sinai).' Then, Allah will raise Gog and Magog and they will swiftly swarm from every mound. Their front forces will reach Lake Tabariah (Sea of Galilee) and will drink all its water. The last of their forces will say as they pass by the lake, `This lake once had water!'

Meanwhile, `Isa, Allah's Prophet, will be cornered along with his companions until the head of a bull will be more precious to them than a hundred Dinars to you today. `Isa, Allah's Prophet, and his companions will invoke Allah for help and Allah will send An-Naghaf (a worm) into the necks of Gog and Magog! The morning will come, and they will all be dead as if it was the death of one soul. Afterwards, `Isa, the Prophet of Allah, will come down with his companions to the low grounds (from Mount At-Tur). They will find that no space of a hand-span on the earth was free of their fat and rot (rotten corpses). `Isa, the Prophet of Allah, and his companions will seek Allah in supplication. Allah will send birds as large as the necks of camels. They will carry them (the corpses of Gog and Magog) and will throw them wherever Allah wills. Afterwards, Allah will send rain that no house made of mud or animal hair will be saved from, and it will cleanse the earth until it is as clean as a mirror. The earth will be commanded (by Allah), `Produce your fruits and regain your blessing.' Then, the group will eat from a pomegranate and will take shelter under the shade of its skin. Milk will be blessed, so much so that the milk-producing camel will yield large amounts that suffice for a large group of people. Meanwhile, Allah will send a pure wind that will overcome Muslims from under their arms and will take the soul of every believer and Muslim. Only the evildoers among people will remain. They will indulge in shameless public sex like that of donkeys. On them, the Hour will begin.)

Imam Ahmad and the collectors of the Sunan also recorded this Hadith. We will mention this Hadith again using the chain of narration collected by Ahmad explaining Allah's statement in Surat Al-Anbiya' (chapter 21),

﴿حَتَّى إِذَا فُتِحَتْ يَأْجُوجُ وَمَأْجُوجُ﴾

(Until, when Ya`juj and Ma`juj (Gog and Magog people) are let loose (from their barrier).) In our time, in the year seven hundred and forty-one, a white minaret was built in the Umayyad Masjid (in Damascus) made of stone, in place of the minaret that was destroyed by a fire which the Christians were suspected to have started. May Allah's continued curses descend on the Christians until the Day of Resurrection. There is a strong feeling that this minaret is the one that `Isa will descend on, according to this Hadith.
