Confession #1076 Female In the Quran,ALLAH calls our attention to a very interesting attribute of the sky: We made the sky a preserved and protected roof yet still they turn away from Our Signs.. (The Quran, 21:32) This attribute of the sky has been proved by scientific research carried out in the 20th century. the atmosphere surrounding the earth filters the light rays coming from space that are harmful to living things. Interestingly, the atmosphere lets only harmless and useful rays- visible light, near ultraviolet light, and radio waves pass through. All of this radiation is vital for life. Near ultraviolet rays, which are only partially let in by the atmosphere, are very important for the photosynthesis of plants and for the survival of all living beings. The majority of the intense ultraviolet rays emitted from the sun are filtered out by the ozone layer of the atmosphere and only a limited-and essential-part of the ultraviolet spectrum reaches the Earth.
