16وَجَعَلَ القَمَرَ فيهِنَّ نورًا وَجَعَلَ الشَّمسَ سِراجًاAli Unal‘And He has set up within them the moon as a light (reflected), and has set up the sun as a lamp.1It is worth noticing that the verse mentions the moon and the sun not as in a (single) heaven, but in or within the seven heavens. This may be a clue to what the Qur’ān means by seven heavens. However, some hold that there is no difference between the moon being mentioned in a single heaven or within seven heavens, since what is meant is that all the heavens are of the same substance and in full harmony with each other.
