Spectroscopy analysis devices were invented in modern times to analyze spectra of the stars and show its structure. These devices showed that the sun is a burning mass with interacting atoms in a nuclear interaction to combine and give huge amounts of energy and heat.

Whereas, the moon like earth is a cold ******, receiving the sun's burning rays and reflects it to earth again. The sun is the source of brightness, which is a scientific fact, while the moon does not shine, but it reflects the light. So, we can say that the sun is the source of light and the moon is the reflector of that light.

Here we find expression, miracles and detail from Qur'an. Allah (be He blessed and exalted) says:(It is He Who made the sun a shining thing and the moon as a light and measured out for it stages that you might know the number of years and the reckoning. Allah did not create this but in truth. He explains the Ayât(proofs, evidence, verses, lessons, signs, revelations, etc.) in detail for people who have knowledge.)[Yunis 5].

Is there a better visualization of scientific facts than this divine expression? In another verse, Allah confirms that the sun is the bright lamp to indicate combustion, as we know; the lamp is the container where you put oil as fuel to burn by chemical reaction producing energy of light.

This is the method used by human until the early twentieth century when people began using the light bulb. So what happens inside the lamb is combustion process and the fuel inside the lamb is the oil that interacts with oxygen in the air to give light and heat. This is what also happens in the sun. If we entered the center of the sun, we find a nuclear- combustion process, fuel here is hydrogen, which reacts with each other to produce light and heat. Look at Allah's expression: (And has made the moon a light therein, and made the sun a lamp) [Noah: 16]. Notice how the Qur'an differentiates between the work of the Moon (a light), and the work of the sun (a lamp).

This accuracy in the koranic scientific terms didn't come by chance, but by the power of Allah Almighty.

God says: (Blessed be He Who has placed in the heaven big stars, and has placed therein a great lamp (sun), and a moon giving light.)[Al-Furqân 61].

Human has benefited from the characteristics that Allah Almighty Has placed in the universes. Maybe the most significant one, of the twenty-first century, in which we live today, is the so-called digital communications which witness great development every day .The question here is: How is the transfer of information on the surface of the globe is done to cover all the parts? It is a distinguished characteristic of the atmosphere, that is to reflect and bounce back the electromagnetic waves, and this is what allows communication and transmission between the continents of this planet without exception.

There are electrically ionized (electrified) layers in the atmosphere that has an advantage of reflecting and bouncing the radio wave when it is sent, just as the light ray reflex and bounces when it strikes a mirror. These layers would act as mirrors for these waves.

As we know from the laws of refraction, the wave coming to a reflector surfaces, falls back in the same angle but in a different direction. This feature made moving messages from one continent to another possible by the reflection of these waves. Above theses layers are magnetic layers surrounding earth from all sides. Their function is to reflect and bounce the deadly cosmic rays coming from space toward Earth, so they reflect it and the rays are scattered in spaces.

The closest atmosphere layer to earth has very important characteristics, it reflects earth temperature and don't leave it to be scattered in space which keeps a constant rate of temperature on earth. So one characteristic of the sky is to bounce or reflect waves of different kinds. This feature has been discovered recently. Everyday, science discovers something new which is related to this feature, the reflection feature, named by the Qur'an by the word (which returns). Surprisingly, we find a great verse in the Qur'an about this feature and described it as a distinguished sky feature, Allah Almighty says: (By the Firmament which returns) [Al tarik: 11].

Again, we repeat our traditional question in this research: from where did this cosmic truth come in a book sent down from more than fourteen centuries? Allah, the creator of the sky, knows about its features, told us about these features to make it a proof for us that every word in the Qur'an is really from Allah (be He blessed and exalted).

The importance of the Earth's atmosphere for life on this planet is no secret to any one. The more science develops, the more we find out about the features and benefits of this wonderful atmosphere which without it, life would not appear on Earth.

Atmosphere extends several hundred of kilometers above the Earth's surface, and its thickness is very low compared to the size of the Earth with a diameter of more than twelve thousand kilometers. What scientists have discovered about the blue cover?

The latest thing, decided and described by scientists about this atmosphere is that it is like a roof, protecting us, in the middle of this dark, cold universe. One of the most important characteristics of atmosphere is that it saves living organisms on earth, with oxygen which is necessary to sustain life. Atmosphere also keeps and stores the coming heat from the sun and maintains moderate and suitable temperature for life. Without this feature, earth planet would be like the moon, one side with temperature more than a hundred degrees, and on the other side less than a hundred degrees below zero.

Millions of meteorites fall into earth everyday but it deterred by the atmosphere and they are burnt because of friction, before reaching earth but only few of them don't burn and reach earth. Moreover, this wonderful roof deters all harmful rays which, if it reach the earth's surface it would burn everything on it. Most dangerous of all, is the ultraviolet radiation. Only the necessary part for life continuity of this radiation reaches us. Earth has a strong magnetic belt for more than two thousand kilometers above the surface; this belt protects the earth from many of the elementary particles floating in space.

After all these facts, which confirm that the sky protect us from many damages, isn't the sky which is the roof that carefully kept by Allah to protect us and keep our lives? This description excites in the Book of Allah from fourteen centuries ago, Allah says: (And we have made the heaven a roof, safe and well guarded. Yet they turn away from its signs (i.e. sun, moon, winds, clouds, etc.). [Al-Anbiyâ’: 32].

Let's consider this scientific expression: (a roof, safe and well guarded). How did this accurate expression come in the book which was in an era when there were only myths but no science? At that time no one knew of the Earth's atmosphere. Who told the Prophet (peace be upon him) about that safe ceiling?
