His vanity stood in his way. Consequently, he felt proud over Adam by virtue of his creation and boasted over him on account of his origin. Thus, this enemy of Allāh is the leader of those who boast, and the fore-runner of the vain. It is he who laid the foundation of factionalism, quarreled with Allāh about the robe of greatness, put on the dress of haughtiness and took off the covering of humility. Do you not see how Allāh made him low on account of his vanity and humiliated him for his feigning to be high? He discarded him in this world and provided for him burning fire in the next world.
