This allegory from Attar's Mosibat Nameh recounts Prophet Muhammad returning from his Ascension (Mi'raj), where he witnessed the vastness of both worlds, yet needing to pledge his belongings to borrow a small amount of barley from a Jewish merchant. Attar uses this narrative to explain the spiritual concept of faqr (spiritual poverty) and detachment from worldly possessions. The story emphasizes that a true spiritual traveler (shab-rav) is indifferent to material wealth or dominion, mirroring how Adam relinquished the eight heavens for a single grain of wheat.
