The sky plays a crucial role in protecting the earth. The sky protects the earth from the lethal rays of the sun. If the sky did not exist then the sun’s radiation would have killed off all life on earth. It also acts like a blanket wrapped around the earth, to protect it from the freezing cold of space. The temperature just above the sky is approximately -270oC. If this temperature was to reach earth then the planet would freeze over instantly. The sky also protects life on earth by warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night. These are some of the many protective functions of the sky.
The Quran asks us to consider the sky in the following verse:
“We made the sky a protective ceiling. And yet they are turning away from Our signs!” (Quran 21:32)
The Quran points to the sky’s protection as a sign of God. The protective properties of the sky were discovered by scientific research conducted in the 20th century.
