Almighty Allah mentions in the Holy Qur’an:
وَبَنَيْنَا فَوْقَكُمْ سَبْعًا شِدَادًا
And (now study the spatial universe ]as well). We built above you seven strong (firmaments). (an-Naba’, 78 : 12)
وَجَعَلْنَا السَّمَاءَ سَقْفًا مَّحْفُوظًا وَهُمْ عَنْ آيَاتِهَا مُعْرِضُونَ
And We made the heavens (i.e., the upper spheres of the earth) a secure roof (in order to save the inhabitants of the earth from adverse effects of fatal forces and aggressive waves shooting towards the earth from space), and they turn away from these signs (of upper spheres).(al-Ambiyā’, 21 : 32)
Shaykh ul Islam Dr. Tahir ul Qadri has mentioned these verses in his renowned work Quranic Encyclopedia as a reference to “Upper spheres of Earth”.

As known by scientific study today, the atmosphere surrounding the Earth consists of seven layers. Each layer serves an important purpose for the benefit of life. 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 to the Earth.
The Troposphere enables water vapor rising from the surface of the Earth to be condensed and turned back as rain. 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 vapor rising from the surface of the Earth to be condensed and turn back down to the Earth as rain.
The magnetosphere layer turns the harmful radioactive particles emitted by the Sun and other stars back into space before they reach the Earth.
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 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.
Thus, each layer of the atmosphere has beneficial attributes for human beings.
It is a great miracle that these facts, which could not possibly be discovered without the technology of the 20th century, were explicitly stated in the Qur’an 1,450 years ago! The fact that this property of the atmosphere’s layers, that was only demonstrated in the recent past was announced centuries ago in the Qur’an, once again demonstrates that the Qur’an is the word of Allah.
