سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ كُلُّ أُمَّتِي مُعَافَاةٌ إِلاَّ الْمُجَاهِرِينَ وَإِنَّ مِنَ الإِجْهَارِ أَنْ يَعْمَلَ الْعَبْدُ بِاللَّيْلِ عَمَلاً ثُمَّ يُصْبِحُ قَدْ سَتَرَهُ رَبُّهُ فَيَقُولُ يَا فُلاَنُ قَدْ عَمِلْتُ الْبَارِحَةَ كَذَا وَكَذَا وَقَدْ بَاتَ يَسْتُرُهُ رَبُّهُ فَيَبِيتُ يَسْتُرُهُ رَبُّهُ وَيُصْبِحُ يَكْشِفُ سِتْرَ اللَّهِ عَنْهُ قَالَ زُهَيْرٌ وَإِنَّ مِنَ الْهِجَارِ
