﴿ وَلَقَدْ جَعَلْنَا فِى ٱلسَّمَآءِ بُرُوجًۭا وَزَيَّنَّٰهَا لِلنَّٰظِرِينَ ﴾

“AND, INDEED, We have set up in the heavens great constellations, and endowed them with beauty for all to behold;”

(And verily in the heaven We have set mansions of the stars) by means of which people are guided in the darkness of the sea or land; it is also said that this means: castles, (and We have beautified it) the sky by means of the stars (for beholders) who look at it.
