Hadith 1637
۞
Certainly, many people have turned away from many a (lasting) benefit (of the next life), for they bent towards the world and spoke with passions. I have been struck with wonder in this matter, upon which people who are self-conceited have agreed. I am providing a cure for their wound but I fear lest it develops into a clot of blood (and becomes incurable).
فَإِنَّ النَّاسَ قَدْ تَغَيَّرَ كَثِيرٌ مِنْهُمْ عَنْ كَثِيرٍ مِنْ حَظِّهِمْ، فَمَالُوا مَعَ الدُّنْيَا، وَنَطَقُوا بِالْهَوى، وَإِنِّي نَزَلْتُ مِنْ هَذَا الْأَمْرِ مَنْزِلًا مُعْجِباً، اجْتَمَعَ بِهِ أَقْوَامٌ أَعْجَبَتْهُمْ أَنْفُسُهُمْ، فإنِّي [وَأَنَا] أُدَاوِي مِنْهُمْ قَرْحاً أَخَافُ أَنْ يَكُونَ عَلَقاً.
