In Farid al-Din Attar's Elahi Nameh, the 'Tale of the Sinner on the Day of Resurrection' illustrates the profound Sufi and Islamic concept of divine grace and the transformative power of sincere repentance (Tawbah). The narrative describes a sinner who, upon reviewing his record on Judgment Day, sees only darkness. However, God commands him to read the back of the record, revealing that because of his remorse, every sin has been replaced with ten good deeds. This reflects the belief that true repentance not only erases sin but converts past transgressions into spiritual merit through God's boundless mercy.
