عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((لَمَّا أُسْرِيَ بِي مَرَرْتُ بِرِجَالٍ تُقْرَضُ شِفَاهُهُمْ بِمَقَارِيضَ مِنْ نَارٍ، فَقُلْتُ: مَنْ هَؤُلَاءِ يَا جِبْرِيلُ؟ قَالَ: هَؤُلَاءِ خُطَبَاءُ مِنْ أُمَّتِكَ يَأْمُرُونَ النَّاسَ بِالْبِرِّ وَيَنْسَوْنَ أَنْفُسَهُمْ وَهُمْ يَتْلُونَ الْكِتَابَ، أَفَلَا يَعْقِلُونَ))
It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When I was taken on the Night Journey (Isra), I passed by some people whose lips were being cut with scissors of fire." I said: "O Jibril! Who are these people?" He said: "These are the preachers of your Ummah who command others to do good but forget their own selves, while they recite the Book. Do they not then understand?"
