This allegory from Attar's Mosibat Nameh describes a thief who enters a dervish's empty house and finds nothing to steal. When the dervish laughs at the thief's futile search, the thief mocks him for living in such poverty. The story illustrates the concept of spiritual poverty (faqr) and detachment from worldly possessions, where the dervish's joy comes from his lack of material concerns, while the thief remains blind to anything beyond material wealth.
