Lamp of utterance .....

"Say: He hath kindled the lamp of utterance, and feedeth it with the oil of wisdom and understanding. Too high is thy Lord, the All-Merciful, for aught in the universe to resist His Faith. He revealeth what He pleaseth through the power of His sovereign might, and protecteth it with a host of His well-favoured angels. He is supreme over His servants and exerciseth undisputed dominion over His creation. He, verily, is the All-Knowing, the All-Wise."
