The prophet (sala Allahu alyhi wasallam )said:
[All my Ummah are forgiven except the ones who publicize their sins.And publicizing is when a man does a sin at night and Allah has covered him,he goes the next day saying:"Hey you,yesterday I did so-and-so."And Allah has shielded him and he wakes up to remove what Allah has shielded for him.](Bukhary)
