The Adornment and Protection of the Heaven comes from Allah

Allah tells us that He has adorned the lowest heaven with the heavenly bodies for those among the people of the earth who look at it. The stars and planets in the sky give light to the people of earth, as Allah says:

وَلَقَدْ زَيَّنَّا السَّمَآءَ الدُّنْيَا بِمَصَـبِيحَ وَجَعَلْنَـهَا رُجُوماً لِّلشَّيَـطِينِ وَأَعْتَدْنَا لَهُمْ عَذَابَ السَّعِيرِ

In the last four verses, (37:7-10): وَحِفْظًا مِّن كُلِّ شَيْطَانٍ مَّارِ‌دٍ ﴿7﴾ لَّا يَسَّمَّعُونَ إِلَى الْمَلَإِ الْأَعْلَىٰ وَيُقْذَفُونَ مِن كُلِّ جَانِبٍ ﴿8﴾ دُحُورً‌ا ۖ وَلَهُمْ عَذَابٌ وَاصِبٌ ﴿9﴾ إِلَّا مَنْ خَطِفَ الْخَطْفَةَ فَأَتْبَعَهُ شِهَابٌ ثَاقِبٌ ﴿10﴾ and [ have made them ] a security against every rebellious shaitan [ shaitan ]. They cannot listen to the Upper Realm and are hit from every side, to be driven off, and for them there is a lasting punishment, (however, if one snatches a little bit, he is pursued by a bright flame - 37:10). It has been said that stars have yet another benefit besides being a decoration of the sky. Through these, wicked shaitan are restrained from approaching the higher levels to eavesdrop. They do that to gather whatever news of the unseen they can gather by reaching the fringes of the sky. But, they are denied the opportunity to listen to what angels say to each other. If some Shaitan picks up even a part of their conversation, and tries to decamp with it, he is hit by a blazing flame, so that he remains unable to pass on this information to his devotees among soothsayers in the world. It is this blazing flame that has been called: شِهَابٌ ثَاقِبٌ (shihab thaqib: meteor). Some details about meteors have appeared in Surah al-Hijr (Ma’ ariful-Qur’ an, volume V. 15:17, 18, pages 303-305). At this place, it should be borne in mind that early Greek scientists believed in meteors being terrestrial substance that rose up with vapors and would burn up when it reached the fire zone. But, the words of the Qur'an, as they appear here, seem to suggest that a meteor is not some terrestrial substance, rather, is something generated only in the upper atmosphere. At this stage, earlier commentators have been saying all along that the Greek assumption about meteors - that it was some terrestrial substance - was no more than a conjecture. Therefore, this cannot be used to raise an objection against the Qur'an. As for the other possibility - that some terrestrial substance rises up and ignites itself in the upper atmosphere - that too offers no contradiction with the Qur'an.

But, once we are in the age of modern scientific discoveries, the question has been put to rest. Astronomers tell us that meteors شِهَابٌ ثَاقِبٌ (shihab thaqib) are small pieces from countless stars, generally of the size of large bricks. They stay in space. One of their groups is known as 'asadiyyah', (Leo, or Lion, out of the signs of Zodiac). It keeps revolving around the sun on its path through the imaginary belt in the heavens. One orbit by it is completed in thirty-three years. Light is emitted in these pieces because of their speed and abrasion against heavenly bodies. These pieces fall mostly during the nights of August 10 and November 27. Then, during the nights of April 20, October 18 and November 28, and on the nights of December 6, 9 and 13, their fallings tapers off. (Tafsir al-Jawahir by Tantawi, page 15, volume 8).
