The Quran enjoins the faithful "to hinder the nafs from lust",[Quran 79:40] and another traditional narration warns that "the worst enemy you have is [the nafs] between your sides."[1] Rumi warns of the nafs in its guise of religious hypocrisy, saying "the nafs has a rosary and a Koran in its right hand, and a scimitar and dagger in the sleeve."[2]
