They ask the sun to expound the words of the shadow, and the True One to explain the utterances of His creatures, could ye but perceive it! Say: O people! The sun offereth naught save the effulgence of its own light and that which appeareth therefrom, whilst all else seek illumination from its rays. Fear God, and be not of the ignorant! Among them also were those who inquired of the darkness about the light. Say: Open thine eyes, that thou mayest behold the brightness which hath visibly enveloped the earth! This, verily, is a light which hath risen and shone forth above the horizon of the Dayspring of divine knowledge with manifest radiance. Would ye ask the Jews whether Jesus was the True One from God, or the idols if Muhammad was an Apostle of His Lord, or inquire from the people of the Qur’án as to Him Who was the Remembrance of God, the Most Exalted, the Most Great?
Say: O people! Cast away, before the splendours of this Revelation, the things that ye possess, and cleave to that which God hath bidden you observe. Such is His command unto you, and He, verily, is best able to command. By My Beauty! My purpose in revealing these words is to cause all men to draw nigh unto God, the All-Glorious, the All-Praised.
Baha’u’llah, The Summons of The Lord of Hosts, par 79-80
