Is it possible for someone to be a hypocrite to himself?

Hypocrisy is showing good while concealing evil. It is of two types: hypocritical belief (nifaq i'tiqadi), which condemns its perpetrator to eternal Hellfire, and practical hypocrisy (nifaq 'amali), which is a major sin. The term "hypocrisy of the self" (nifaq al-nafs) does not exist in Islamic law. Rather, there are warnings against deceiving oneself by persistent indulgence in disobedience. A person might think they are deceiving others, while in reality, they are deceiving themselves and leading themselves to ruin, believing they are doing good to themselves. A Muslim must be astute to the whisperings and schemes of the self, which portray falsehood as truth and entice them. Whoever holds themselves accountable and restrains the self from its desires will be saved, and whoever is deceived by their self will be ruined by it. Ibn al-Qayyim likened the self to a partner who must be conditioned, monitored, and held accountable. This conditioning focuses on preserving the seven limbs, which are the basis of salvation or perdition, and daily accountability provides ease from the reckoning of tomorrow.
