Sin displeasing you better than pride-inducing virtue

[1] The person who feels ashamed and repentant after committing sin and offers repentance before Allāh remains safe from the penalty of that sin and deserves the reward of repentance: while the person who after doing a virtuous deed begins to feel superiority over others, and being proud of his virtues thinks that he has no apprehension whatever, destroys his virtue and remains deprived of the reward of the virtuous deed. Obviously, he who has erased the blot of his sin by repentance will be better than he who has ruined his action by being proud of it, and having not repented of it either.
