This allegory in Attar's Mosibat Nameh describes a scholar who has memorized four hundred boxes of knowledge and devotes all his time to worship. Despite his extensive learning and religious devotion, a prophet of his time receives a divine revelation that the scholar is destined for hell due to his secret love for the material world. The tale illustrates that formal scholarship and external acts of obedience are spiritually useless if the heart remains attached to worldly desires, warning that even a fraction of worldly love prevents divine acceptance.
