All may be forgiven except for the ones who publicize their sins

I heard the Messenger of Allah ﷺ say: “All of my Ummah will be pardoned except those who publicize their sins. Indeed, part of shamelessness is that a man commits a deed at night and then morning comes while Allah has concealed him. Yet he says, ‘O so-and-so, last night I did such-and-such,’ while his Lord had covered him during the night, and in the morning he reveals Allah’s covering from himself.”

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ: «كُلُّ أُمَّتِي مُعَافًى إِلاَّ الْمُجَاهِرِينَ، وَإِنَّ مِنَ الْمَجَانَةِ أَنْ يَعْمَلَ الرَّجُلُ بِاللَّيْلِ عَمَلاً ثُمَّ يُصْبِحَ وَقَدْ سَتَرَهُ اللَّهُ فَيَقُولَ: يَا فُلاَنُ عَمِلْتُ الْبَارِحَةَ كَذَا وَكَذَا، وَقَدْ بَاتَ يَسْتُرُهُ رَبُّهُ، وَيُصْبِحُ يَكْشِفُ سِتْرَ اللَّهِ عَنْهُ».
