This allegory from Attar's Elahi Nameh recounts a madman who asks a salesman to sell his rough blanket (kilim). The salesman initially ridicules its harshness, comparing it to a hedgehog, but later sells it to a dervish as a luxurious silk blanket in exchange for gold. Witnessing this, a Sufi cries out in amazement at how a rough blanket is suddenly transformed into silk, and worthless clay into a precious pearl. The narrative serves as a spiritual satire on worldly greed and deception, illustrating how the illusion of material desires can falsely elevate the valueless and blind individuals to true spiritual reality.
