Abdul Qadir Jelani, a great Sufi saint, was one day engaged in prayer, when in a vision he saw the semblance of an angel, who addressed him, saying, "O thou who hast prayed continuously all thy life, to thee God sends the good tidings that no more prayers are required of thee." The saint, recognizing the tempter, replied, "Begone, thou wicked one, I recognize thee in spite of thy angelic guise: thou art a devil come to tempt me. All the holy ones have passed their lives in prayer, and how can I deem myself worthy to be exempt from it?" On hearing these words the evil one vanished.
