عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ((مَرَرْتُ لَيْلَةَ أُسْرِيَ بِي عَلَى قَوْمٍ تُقْرَضُ شِفَاهُهُمْ بِمَقَارِيضَ مِنْ نَارٍ قَالَ قُلْتُ مَنْ هَؤُلَاءِ قَالُوا خُطَبَاءُ مِنْ أَهْلِ الدُّنْيَا كَانُوا 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: On the night of Isra, I passed by some people whose lips were being cut with scissors of fire. I asked: Who are these people? It was said: These are the preachers of the world, who enjoin righteousness upon the people but forget their own selves, while they also recite the Book of Allah. Do they not then understand?
