رسول الله (صلی الله علیه و آله):
بَينَما موسى عليه السلام جالِسا إذ أقبَلَ إبليسُ ... قالَ موسى: فَأخبِرْني بِالذَّنبِ الذي إذا أذنَبَهُ ابنُ آدَمَ استَحوَذتَ علَيهِ. قالَ: إذا أعجَبَتهُ نَفسُهُ، واستَكثَرَ عَمَلَهُ، وصَغُرَ في عَينِهِ ذَنبُهُ.
The Prophet Muhammad (S):
Moses (as) was once sitting down when Iblis [Satan] approached him ... Moses asked him, 'So inform me about the sin which if the son of Adam were to commit would give you mastery over him.' He replied, 'When he feels proud of himself (has a sense of self-admiration), overrates his good deeds, and deems his sin insignificant.
