In Book Four of Rumi's Masnavi, Moses attempts to awaken faith in Pharaoh by revealing the tyrant's most intimate, hidden nightmares and visions of the unseen (zahr al-ghayb). Moses describes Pharaoh's dreams of terror—such as his garments burning, his mouth and eyes sewn shut, animal attacks, and drowning in sewage or blood—which Pharaoh kept secret from others. Rumi employs the striking metaphor of a dark-skinned person (zangi) who, upon seeing his own ugly reflection in a mirror, gets angry and defiles the mirror. This teaching illustrates that the prophet or spiritual guide acts as a pure, flawless mirror reflecting the seeker's inner corruption; denying the revelation or hating the messenger is merely a refusal to face one's own spiritual ugliness.
