Evaluating the Importance of Sky in Human Health and Life, From the Viewpoint of Holy Quran

Context: holy quran is the last and the most complete scripture which god has revealed to guide human beings. observing quranic commands results in satisfaction of the lord, worldly prosperity and salvation in hereafter. discovering secrets of creation and miracles of quran, through modern sciences and technologies, is a way for researchers and intellectuals to ponder on wisdom of god. the current study has evaluated the importance of sky in human health and life from the viewpoint of holy quran. evidence acquisitions: verses, regarding the properties of sky affecting human life and health, were gathered from holy quran, and then they were discussed by the use of interpretive references and also physical, biological, and medical findings. results: according to holy quran, sky has been mentioned in two general concepts as physical (tangible), and spiritual. “tangible sky” includes atmosphere, and spaces over atmosphere, heavenly planets and their position. holy verses indicate the point that “tangible sky” has been created with the property of “reserved roof” and “returning” characteristics. water vapor from oceans and seas rise to sky, and return to earth as rain and snow, and also reflection of hazardous ultraviolet radiation and other fatal radioactive rays resulted from solar storms to the extra-atmospheric spaces, are examples of the important evidence of “returning”. also, earth is protected against meteorites. descending the vital element of iron from other planets to earth is a clear example for the importance of sky in the concept of heavenly planets. conclusions: fourteen centuries ago, holy quran has indicated the importance of “tangible sky” in man`s life and health. scientists of the current century have just realized some properties and applications of corporeal sky, by the help of modern technologies. “spiritual sky” is the hidden realm of almighty and the place of his government over all creatures. this sky will be never discovered through experimental sciences and the only way to identify it is to believe in god.
