This allegory from Attar's Mosibat Nameh describes a dream in which a Sheikh encounters a pious man who cannot return his greeting. The man explains that the door to performing acts of worship and obedience (ta'at) is permanently closed after death. He expresses profound regret for not utilizing every moment of his earthly life for spiritual devotion, emphasizing the Sufi principle that the material world is the only place where one can actively cultivate spiritual merit through obedience.
