عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ إِذَا قَالَ الرَّجُلُ هَلَكَ النَّاسُ ‏ فَهُوَ أَهْلَكُهُمْ

2623 صحيح مسلم كتاب البر والصلة والآداب باب النهي عن قول هلك الناس

قال النووي وَاتَّفَقَ الْعُلَمَاءُ عَلَى أَنَّ هَذَا الذَّمَّ إِنَّمَا هُوَ فِيمَنْ قَالَهُ عَلَى سَبِيلِ الْإِزْرَاءِ عَلَى النَّاسِ وَاحْتِقَارِهِمْ وَتَفْضِيلِ نَفْسِهِ عَلَيْهِمْ وَتَقْبِيحِ أَحْوَالِهِمْ لِأَنَّهُ لَا يَعْلَمُ سِرَّ اللَّهِ فِي خَلْقِهِ
