In Sufi literature, particularly in the works of Farid al-Din Attar, the zunnar (a girdle traditionally worn by non-Muslims, such as Christians or Zoroastrians, in medieval Islamic societies) is often used as a provocative symbol. While outwardly representing infidelity or heresy, Sufi narrators subvert its meaning to symbolize ultimate spiritual humility, the renunciation of external piety, and the acknowledgement of one's own hidden idolatry (shirk). When a revered mystic like Bayazid Bastami is depicted requesting to wear the zunnar on his deathbed, it represents the complete shedding of his ego, religious pride, and reputation as a spiritual master. By adopting the symbol of the 'infidel', the dying mystic confesses his existential nothingness and utter dependency before the absolute majesty of the Divine.
