وَلَقَدْ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ يَخْرُجُ مِنْ أُمَّتِي قَوْمٌ يُسِيئُونَ الْأَعْمَالَ يَقْرَءُونَ الْقُرْآنَ لَا يُجَاوِزُ حَنَاجِرَهُمْ قَالَ يَزِيدُ لَا أَعْلَمُ إِلَّا قَالَ يَحْقِرُ أَحَدَكُمْ عَمَلَهُ مِنْ عَمَلِهِمْ يَقْتُلُونَ أَهْلَ الْإِسْلَامِ فَإِذَا خَرَجُوا فَاقْتُلُوهُمْ ثُمَّ إِذَا خَرَجُوا فَاقْتُلُوهُمْ ثُمَّ إِذَا خَرَجُوا فَاقْتُلُوهُمْ فَطُوبَى لِمَنْ قَتَلَهُمْ وَطُوبَى لِمَنْ قَتَلُوهُ كُلَّمَا طَلَعَ مِنْهُمْ قَرْنٌ قَطَعَهُ اللَّهُ عَزَّ وَجَلَّ فَرَدَّدَ ذَلِكَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عِشْرِينَ مَرَّةً أَوْ أَكْثَرَ وَأَنَا أَسْمَعُ
مسند امام احمد بن حنبل · Hadith 5562.3
(It was narrated that Ibn 'Umar said:) and I heard the Messenger of Allah (PBUH) say: "There will emerge from among my ummah people who do evil deeds; they will recite the Qur'an but it will not go any further than their throats.” Yazeed said: I do not know but that he said: "One of you would regard his (good) deeds as insignificant compared to theirs. They will kill the people of Islam. When they emerge, kill them; when they emerge, kill them; when they emerge, kill them; and glad tidings to the one who kills them, glad tidings to the one who kills them. Every time a head of theirs appears, Allah (PBUH) will cut it off "Tte Messenger of Allah (PBUH) rented that twenty times or more, whilst I was listening.
