Al-Anbiyaa (The Prophets)

32. “And We set up the heaven as a roof well-protected, and yet they turn away from its signs.”

In view of the fact that the mere stillness of the earth is not enough for the comfort of human’s life and he must also be secured from the upward, in this verse the Qur’an adds:

“And We set up the heaven as a roof well-protected, and yet they turn away from its signs.”

The objective of ‘the heaven’ here is the atmosphere which has encompassed the earth from every side. According to the researches of the concerning scientists, the depth of this atmosphere reaches to hundreds kilometers.

This depth of weather, which apparently is tender, is composed of oxygen and different gases, is so firm and strong that no disturbing thing that comes toward it can destroy it. It protects the earth against aerolites which continuously fall down, day and night, and are more dangerous than any bullet.

Moreover, the harmful parts of the sunrays are taken by it. Thus, it guards the earth against the fatal outside rays that comes towards it from cosmos.
