In Farid al-Din Attar's Conference of the Birds, Abbasah's speech presents a powerful metaphor characterizing the carnal ego (nafs) as an 'infidel' (kafar). The poem asserts that every individual harbors and nurtures this disobedient, unbelieving entity within themselves. By emphasizing how difficult it is to 'kill' this inner infidel, the passage highlights a core Sufi teaching: the ultimate spiritual struggle is not against external enemies, but against the stubborn, rebellious nature of one's own lower self.
