This allegory in Attar's Mosibat Nameh recounts an incident during a sermon by Rukn al-Din Akkafi, which is interrupted by a commotion over a stolen shoe. Akkafi uses the moment to teach that if God were to lift the veil of divine protection (sattariyyat) and reveal everyone's hidden sins, the very person complaining might be exposed as the foremost thief. The parable highlights themes of divine grace, the universality of human flaws, and the realization that human innocence relies heavily on God's mercy in concealing sins.
