The Returning Sky

The 11^th verse of Surat at-Tariq in the Qur’an, refers to the “returning” function of the sky :
(By Heaven with its cyclical systems.)
(Surat at-Tariq, 11)

This word interpreted as “cyclical” in Qur’an translations also has meanings of “sending back” or “returning”.

As known, the atmosphere surrounding the earth consists of many layers.

Each layer serves an important purpose for life’s benefit. Research has revealed that these layers have the function of turning the materials or rays they are exposed to back into space or back down on earth. Now let us examine with a few examples this “recycling” function of the layers encircling the earth.

The troposphere, 13 to 15 kilometers above the earth, enables water vapor rising from the surface to be condensed and turn back down to the earth as rain.

The ozone layer, at an altitude of 25 kilometers, reflects harmful radiation and ultraviolet light coming from space and turns both back into space.

The ionosphere reflects radio waves broadcast from the earth back down to different parts of the world just like a passive communications satellite and thus makes wireless communication, radio, and television broadcasting possible over long distances.

The fact that this property of the sky’s layers, which could only be scientifically discovered recently, was declared centuries ago in the Qur’an, once again demonstrates that the Qur’an is the word of God.

The presence of water is essential for life on Earth. One of the factors acting in the formation of water is the Troposphere, one of the layers of the atmosphere. The troposphere layer enables water vapour rising from the surface of the Earth to be condensed and turn back down to the Earth as rain.

The atmosphere layer that blocks the rays that might be fatal to life on Earth is the Ozonosphere. The Ozonosphere turns harmful cosmic rays like ultraviolet back to space, hence preventing them from reaching the Earth and harming life.

Each layer of the atmosphere has beneficial attributes for human beings. The Ionosphere layer, one of the upper layers of the atmosphere, for example, reflects radio waves broadcast from a certain centre back down to the Earth, thus enabling broadcasts to be received from long distances.
