– It is narrated from Imam Baqir (AS) who said:

Two men entered the Mosque, one of them a pious and the other was a corrupt person, and when they were leaving the Mosque, the corrupt became pious and the pious one became corrupt. The reason for this was that the pious when entering the Mosque was thinking that because of his prayers to God, he is favoured by Allah (SWT), and he was busy thinking about this point. But the corrupt person entered the Mosque with regrets about his past, and was repenting to God for all his sins and asking for forgiveness [1].
