The concept of pride embraces all those aspects of vanity found in those who are proud of their actions, little knowing what their end will be. Whoever is proud of himself and his actions has strayed off the path of right guidance and has claimed what is not his.
Anyone who claims something to which he has no right is a liar, even if he conceals his claim for a long time. The first thing which happens to the proud man is that he is stripped of his object of pride, so that he will know that he is contemptible and incapable, and will testify against himself; and that will be a firmer proof against him. This was the case with Iblis.
Pride is a plant whose seed is disbelief, whose earth is hypocrisy, and whose water is transgression. Its branches are ignorance, its leaves are misguidance, and its fruit is being cursed to remain in the Fire forever. Whoever chooses pride has sowed disbelief and cultivated hypocrisy. It is inevitable that it must bear its fruit and he will end up in the Fire.
