"The Messenger of Allah said: 'At the end of time there will appear a people with new teeth (i.e., young in age), with foolish minds. They will speak the best words ever uttered by mankind and they will recite the Qur'an, but it will not go any deeper than their collarbones. They will pass through Islam like an arrow passes through its target. Whoever meets them, let him kill them, for killing them will bring a reward from Allah for those who kill them." (Using translation from Ibn Mājah 168)
قَالَ رَسُولُ اللهِ ﷺ يَخْرُجُ قَوْمٌ فِي آخِرِ الزَّمَانِ سُفَهَاءُ الْأَحْلَامِ أَحْدَاثٌ أَوْ قَالَ حُدَثَاءُ الْأَسْنَانِ يَقُولُونَ مِنْ خَيْرِ قَوْلِ النَّاسِ يَقْرَءُونَ الْقُرْآنَ بِأَلْسِنَتِهِمْ لَا يَعْدُو تَرَاقِيَهُمْ يَمْرُقُونَ مِنَ الْإِسْلَامِ كَمَا يَمْرُقُ السَّهْمُ مِنَ الرَّمِيَّةِ فَمَنْ أَدْرَكَهُمْ فَلْيَقْتُلْهُمْ فَإِنَّ فِي قَتْلِهِمْ أَجْرًا عَظِيمًا عِنْدَ اللهِ لِمَنْ قَتَلَهُمْ
