In Jalaluddin Rumi's Masnavi, the harsh judgment cast upon sinners by the angels Harut and Marut serves as a profound warning against spiritual arrogance and self-conceit. Rumi observes that individuals who possess deep-seated flaws often project their own inner ugliness onto others. He illustrates this psychological projection through the metaphor of an ugly man who, upon seeing his reflection in a mirror, turns away in anger rather than acknowledging his own face. Furthermore, Rumi severely critiques self-righteous individuals who mask their egotistical anger and harsh condemnation of others as the 'zeal of religion' ($حمیت دین$). He asserts that this hypocritical fury stems from a hellish pride within their own souls. In stark contrast, Rumi explains that genuine religious zeal is a divine, life-giving fire; rather than consuming others in judgment, it 'turns a world verdant'. Ultimately, Rumi emphasizes that any spiritual purity ($عصمت$) one possesses is not an innate achievement, but solely a reflection of God's continuous grace and protection.
