In Attar's Conference of the Birds, the tale of the heedless man complaining about the devil reveals that Iblis's domain is the material world (dunya). The devil claims he only attacks those who interfere with his worldly territory while claiming to be on a spiritual path. The central lesson is that true protection from satanic influence requires complete detachment from worldly desires; as long as a person clings to the world, they remain vulnerable to its ruler.
