And We have certainly beautified the nearest heaven with stars and have (67:5)

Almuntakhab Fi Tafsir Alquran Alkarim

And We decorated the lowermost heaven with lamps (or heavenly bodies), some of them adapted to be like weapons in pursuit of the evil ones for whom We have prepared torture in the blazes of Hell

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(67:5) We have adorned the lower heaven *9 with lamps, *10 and have made them a means to drive away the satans. *11 We have prepared for them the chastisement of the Blazing Fire.

And We have certainly beautified the nearest heaven with stars and have meaning

*9) "The nearest heaven": the heaven the stars and planets of which can be seen with the naked eye; the objects beyond that which can be seen only through telescopes are the distant heaven; and the heavens still farther away are those which have not yet been seen even with telescopes.
*10) The word masabih in the original has been used as a common noun, and therefore, automatically gives the meaning of the lamp's being splendid and glorious. It means: "We have not created this universe dark, dismal and desolate, but have decked and decorated it with stars, the glory and grandeur of which at night strike man with amazement."
*11) 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 Qur'an, it has been stated that there is absolutely no possibility of the Satans' ascending to the heavens and bringing news of the unseen. (For explanation, see E.N.'s 9-12 of AI-Hijr, E.N.'s 6, 7 of As-Saaffat).
As for the truth about meteorites, man's information in this regard is still without a scientific basis. However, the theory which seems best to account for all the facts known today and the information gathered from the examination of the meteorites fallen on the earth, is that meteorites originate from the disintegration of one or more planets and wander in space and sometimes fall to the earth under its gravitational pull. (See Erlcyclopaedia Britannica, vol. XV, under "Meteorites").

ہم نے تمہارے قریب کے آسمان کو عظیم الشان چراغوں سے آراستہ کیا ہے اور اُنہیں شیاطین کو مار بھگانے کا ذریعہ بنا دیا ہے اِن شیطانوں کے لیے بھڑکتی ہوئی آگ ہم نے مہیا کر رکھی ہے
