The thing everybody on this earth agrees upon is this Universe, and for all of them the sun is the sun, the moon is the moon, the day is the day, and the same goes for the mountains, lakes, seas, rivers, fish, birds, plants, inanimate objects, minerals, and creatures.
 This Universe is the first fundamental which bespeaks Allah’s existence, His Perfection and Oneness. It is a silent Qur'an any man can read, whether Arab or not. There is, thus, a general agreement on the Universe, from which everybody benefits. Hence, it is the greatest fundamental of faith. The Universe denotes Allah because it contains wisdom clearly pointing to the All-Wise; it contains mercy pointing to Most Merciful; it contains organization pointing to the Organizer; it contains creatures pointing to the Creator; it contains subtlety pointing the Subtle One and beauty pointing to the Beautiful One. In it are manifested Allah’s Glorious Names and His Excellent Attributes. The Universe is a fundemental agreed upon and complied with by all people, so in times of misguiding, tempting, and different idiological disturbances the Universe remains as the primary fundamental of faith.

 How come man, in spite of his arrogance and reluctance, doesn’t submit to those astonishing Signs? How come he isn't amazed at a galaxy 20 billion light years away from us? Given that light travels at the speed of 300 thousand kilometers per second, how far does it travel in a minute? In an hour? In a day? In a month? In a year? In 20 billion years? Allah Most High says:

“On the earth are Signs for those of assured Faith.”
