Messenger of Allah (ﷺ) said, "Every one of my followers will be forgiven except those who expose (openly) their wrongdoings. An example of this is that of a man who commits a sin at night which Allah has covered for him, and in the morning, he would say (to people): "I committed such and such sin last night,' while Allah had kept it a secret. During the night Allah has covered it up but in the morning he tears up the cover provided by Allah Himself."
