Bukhari Hadith on not lift the veil on sin to others Seek forgiveness from Allah

Abu Hurairah Radiyallahu 'anhu narrates: 
I heard Rasullullah Sallallahu 'alaihi wasallam saying: All of my followers will be forgiven, except those who sin openly. Sinning openly is that a man commits an evil deed at night; and Allah keeps it hidden then getting up at dawn he says: O so and so, I committed such and such sin last night. He spent the night in such a way that Allah veiled his sin, and at dawn he himself lifted the veil which Allah had put on him. (Bukhari)
