حَدَّثَنِى زُهَيْرُ بْنُ حَرْبٍ حَدَّثَنَا مُعَلَّى بْنُ مَنْصُورٍ حَدَّثَنَا سُلَيْمَانُ بْنُ بِلاَلٍ حَدَّثَنَا سُهَيْلٌ عَنْ أَبِيهِ عَنْ أَبِى هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- قَالَ « لاَ تَقُومُ السَّاعَةُ حَتَّى يَنْزِلَ الرُّومُ بِالأَعْمَاقِ أَوْ بِدَابِقَ فَيَخْرُجُ إِلَيْهِمْ جَيْشٌ مِنَ الْمَدِينَةِ مِنْ خِيَارِ أَهْلِ الأَرْضِ يَوْمَئِذٍ فَإِذَا تَصَافُّوا قَالَتِ الرُّومُ خَلُّوا بَيْنَنَا وَبَيْنَ الَّذِينَ سَبَوْا مِنَّا نُقَاتِلْهُمْ. فَيَقُولُ الْمُسْلِمُونَ لاَ وَاللَّهِ لاَ نُخَلِّى بَيْنَكُمْ وَبَيْنَ إِخْوَانِنَا. فَيُقَاتِلُونَهُمْ فَيَنْهَزِمُ ثُلُثٌ لاَ يَتُوبُ اللَّهُ عَلَيْهِمْ أَبَدًا وَيُقْتَلُ ثُلُثُهُمْ أَفْضَلُ الشُّهَدَاءِ عِنْدَ اللَّهِ وَيَفْتَتِحُ الثُّلُثُ لاَ يُفْتَنُونَ أَبَدًا فَيَفْتَتِحُونَ قُسْطُنْطِينِيَّةَ فَبَيْنَمَا هُمْ يَقْتَسِمُونَ الْغَنَائِمَ قَدْ عَلَّقُوا سُيُوفَهُمْ بِالزَّيْتُونِ إِذْ صَاحَ فِيهِمُ الشَّيْطَانُ إِنَّ الْمَسِيحَ قَدْ خَلَفَكُمْ فِى أَهْلِيكُمْ. فَيَخْرُجُونَ وَذَلِكَ بَاطِلٌ فَإِذَا جَاءُوا الشَّامَ خَرَجَ فَبَيْنَمَا هُمْ يُعِدُّونَ لِلْقِتَالِ يُسَوُّونَ الصُّفُوفَ إِذْ أُقِيمَتِ الصَّلاَةُ فَيَنْزِلُ عِيسَى ابْنُ مَرْيَمَ فَأَمَّهُمْ فَإِذَا رَآهُ عَدُوُّ اللَّهِ ذَابَ كَمَا يَذُوبُ الْمِلْحُ فِى الْمَاءِ فَلَوْ تَرَكَهُ لاَنْذَابَ حَتَّى يَهْلِكَ وَلَكِنْ يَقْتُلُهُ اللَّهُ بِيَدِهِ فَيُرِيهِمْ دَمَهُ فِى حَرْبَتِهِ ».

It was narrated from Abu Hurairah that the Messenger of Allah (s.a.w) said: "The Hour will not begin until the Byzantines camp at Al-A'maq or Dabiq, and an army composed of the best people on earth at that time will go out from Al-Madinah to meet them. When they arrange themselves in ranks, the Byzantines will say: 'Do not stand between us and those who took prisoners from us; let us fight them.' The Muslims will say: 'No by Allah, we will never let you reach our brothers.' Then they will fight them, and one-third will flee, whose repentance will never be accepted by Allah; one-third will be killed, and they are the best of martyrs before Allah; and one-third will prevail and will never succumb to any Fitnah, and they will conquer Constantinople. While they are dividing the spoils, having hung their swords on the olive trees, the Shaitan will shout out among them: Al-Masih has taken your place among your families. So they will march, but that will be false news. When they reach Ash-Sham, he will emerge, and while they are still preparing for battle, drawing up their ranks, the Iqamah for prayer will be called, and 'Eisa bin Mariam will descend, and will lead them. When the enemy of Allah sees him, he will melt as salt melts in water. If he left him alone, he would still melt until he was destroyed, but Allah will kill him by his hand, and he will show them his blood on his lance."
