Allah says in the Noble Quran:
وَجَعَلْنَا السَّمَاءَ سَقْفًا مَحْفُوظًا ۖ وَهُمْ عَنْ آيَاتِهَا مُعْرِضُونَ
And We have made the heaven a roof, safe and well guarded. Yet they turn away from its signs (i.e. sun, moon, winds, clouds, etc.).
اور آسمان کو ایک محفوظ چھت بنا دیا۔ پھر بھی یہ لوگ اللہ کی نشانیوں کی طرف توجہ نہیں کرتے۔
[Al-Quran, Surat Al-Anbiyah 21, Verse 32, Part 17]
This attribute of the sky has been proved by scientific research carried out in the 20th century: The atmosphere surrounding the Earth serves crucial functions for the continuity of life. While destroying many meteors - big and small - as they approach the Earth, it prevents them from falling to Earth and harming living things.
In addition, the atmosphere filters the light rays coming from space that are harmful to living things. The most striking feature of this function of the atmosphere is that it lets only harmless and useful rays-visible light, near ultraviolet light and radio waves pass through. All of this radiation is vital for life. Near ultraviolet rays, which are only partially let in by the atmosphere, are very important for the photosynthesis of plants and for the survival of all living things. The majority of the intense ultraviolet rays emitted from the Sun are filtered out by the ozone layer of the atmosphere. Only a limited and essential part of the ultraviolet spectrum reaches the Earth.
The protective function of the atmosphere does not end here. The atmosphere also protects the Earth from the freezing cold of the space, which is approximately -2700C (-4540F).
It is not only the atmosphere that protects the Earth from harmful effects. In addition to the atmosphere, the Van-Allen Belt - the layer caused by the magnetic field of the Earth - also serves as a shield against the harmful radiation that threatens our planet. This radiation, which is constantly emitted by the Sun and other stars, is deadly to living things. If the Van-Allen belt did not exist, the massive outbursts of energy called solar flares that frequently occur in the Sun would destroy all life on Earth.
In short, a perfect system is at work high above the Earth. It surrounds our world and protects it against external threats. Centuries ago, Allah Almighty informed us in the Qur'an of the world’s atmosphere functioning as a protective shield.
