67.5. And, indeed, We have adorned the lowest heaven (the heaven of the world) with lamps (stars), and made (out of) them missiles to drive away devils; and for them, We have prepared (in the Hereafter) the punishment of the Blaze.
(Commentary tafeemul Quran)-This does not mean that the stars themselves are pelted at the Satans, nor that the meteorites shoot out only to drive away the Satans, but it means that the countless meteorites which originate from the stars and wander in space at tremendous speeds and which also fall to the earth in a continuous shower prevent the Satans of the earth from ascending to the heavens. Even if they try to ascend heavenward these meteorites drive them away. This thing has been mentioned here because the Arabs believed about the soothsayers, and this also was the claim made by the soothsayers themselves, that the Satans were under their control, or that they had a close contact with them, and through them they received news of the unseen, and thus, could foretell the destinies of the people. That is why at several places in the Quran, it has been stated that there is absolutely no possibility for the Satans ascending to the heavens and bringing news of the unseen. (For explanation, see E.Ns 9-12 of Surah Al-Hijr, E.Ns 6, 7 of Surah As- Saaffat).
(Commentary Yusuf Ali)-Taking the physical heavens, we can imagine the supreme melody of harmony- guarded from every disturbing force. If by any chance any rebellious force of evil seeks to obtain, by stealth, a sound of that harmony to which all who make themselves constant are freely invited, it is pursued by a shooting star, for there can be no consonance between evil and good.
driven away with stones, rejected, accursed
A shooting star.
‘We have indeed decked the lower heaven with beauty (in) the stars,-‘ Al-Quran (37:6)
‘(For beauty) and for guard against all obstinate rebellious evil spirits,’ Al-Quran (37:7)
(Commentary Tafeemul Quran)-Lower heaven”: The nearest heaven which can be seen with the naked eye, without the help of a telescope. The worlds beyond which can be seen through the telescopes of different powers, and the worlds which have not so far been observed through any means, are the distant heavens. In this connection, one should also note that “sama” is not something definite and determined, but man generally has been using this word and its other synonyms for the heavens since the earliest times.
6. That is, heaven is not merely empty space so that anyone who likes may enter it, but it has been fortified strongly, and its different regions have been bounded by such strong barriers that it is impossible for any rebel satan to exceed them. Every star and planet in the universe has its own circle and sphere escaping from which is as difficult as entering it. With the naked eye one can only see empty space, but, in reality, there are countless regions in space which have been even more strongly fortified and protected than they could be by steel walls. One can imagine and estimate the strength of these barriers by the difficulties man is experiencing in the way of reaching the moon, which is our nearest neighbor in space. Similar difficulties prevent the other creation of the earth, the jinns, from ascending towards the heavens.
