In Farid al-Din Attar's Elahi Nameh, the tale of the Sufi man who falls in love with Zubaydah serves as a powerful allegory for the necessity of absolute sincerity (ikhlas) in spiritual devotion. When the Sufi readily accepts a bag of gold to stop his shouting, Zubaydah orders him to be flogged, exposing his love as a lie. Through this narrative, Attar illustrates that true spiritual love ('Ishq) is incorruptible and cannot be bartered for worldly wealth or comfort. The true seeker must desire only the Divine Beloved, rejecting any material distractions or compromises that expose insincerity.
