Abu Sa’id al-Khudri reported: The Prophet, peace and blessings be upon him, said, “There will come a people from the east, who recite the Quran but it does not go beyond their throats. They will go out of the religion, just as an arrow pierces through its target, and they will not return to it, just as the arrow does not return to the bow.” It was said, “What will be their sign?” The Prophet said, “Their sign is shaving.” Or he said, “It is shearing.”

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ يَخْرُجُ نَاسٌ مِنْ قِبَلِ الْمَشْرِقِ وَيَقْرَءُونَ الْقُرْآنَ لَا يُجَاوِزُ تَرَاقِيَهُمْ يَمْرُقُونَ مِنْ الدِّينِ كَمَا يَمْرُقُ السَّهْمُ مِنْ الرَّمِيَّةِ ثُمَّ لَا يَعُودُونَ فِيهِ حَتَّى يَعُودَ السَّهْمُ إِلَى فُوقِهِ قِيلَ مَا سِيمَاهُمْ قَالَ سِيمَاهُمْ التَّحْلِيقُ أَوْ قَالَ التَّسْبِيدُ
