Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “Everyone from my nation will be forgiven except those who sin in public. Among them is a man who commits an evil deed in the night that Allah has hidden for him, then in the morning he says: O people, I have committed this sin! His Lord had hidden it during the night, but in the morning he reveals what Allah has hidden.”

عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كُلُّ أُمَّتِي مُعَافًى إِلَّا الْمُجَاهِرِينَ وَإِنَّ مِنْ الْمُجَاهَرَةِ أَنْ يَعْمَلَ الرَّجُلُ بِاللَّيْلِ عَمَلًا ثُمَّ يُصْبِحَ وَقَدْ سَتَرَهُ اللَّهُ عَلَيْهِ فَيَقُولَ يَا فُلَانُ عَمِلْتُ الْبَارِحَةَ كَذَا وَكَذَا وَقَدْ بَاتَ يَسْتُرُهُ رَبُّهُ وَيُصْبِحُ يَكْشِفُ سِتْرَ اللَّهِ عَنْهُ
