أَنَّ رَسُولَ اللَّهِ ﷺ قَرَأَ هَذِهِ الآيَةَ (اتَّقُوا اللَّهَ حَقَّ تُقَاتِهِ وَلاَ تَمُوتُنَّ إِلاَّ وَأَنْتُمْ مُسْلِمُونَ ) قَالَ رَسُولُ اللَّهِ ﷺ لَوْ أَنَّ قَطْرَةً مِنَ الزَّقُّومِ قُطِرَتْ فِي دَارِ الدُّنْيَا لأَفْسَدَتْ عَلَى أَهْلِ الدُّنْيَا مَعَايِشَهُمْ فَكَيْفَ بِمَنْ يَكُونُ طَعَامَهُ
