Kibr in the Akhlaq Tradition

Al Ghazali's Ihya Ulum al Din, the Revival of the Religious Sciences, gives kibr an entire book of its own within the section on destructive vices, and his definition is precise rather than merely condemnatory: kibr is not simply thinking well of oneself but a specific refusal, hasan al haqq wa ghamt al nas in the classical formula quoted across later akhlaq literature, rejecting truth when it contradicts one's own view and looking down on other people. He traces the paradigm case to Iblis, who is described in the Quran as refusing to prostrate before Adam on the explicit ground that he, made of fire, considered himself superior to a being made of clay, a refusal the Quranic narrative frames as the founding act of arrogance against God's command rather than as one sin among equals.

The Study Quran's commentary on this passage notes that Iblis's fault is treated across the exegetical tradition as qualitatively different from Adam's later error, since Adam disobeys and immediately repents, while Iblis argues, justifying his disobedience through a claim of merit, a distinction commentators read as showing why arrogance is judged more severe than an ordinary lapse: it refuses the very possibility of being wrong.
