The Criterion - 25:61
Exalted is He who has set constellations in the sky and placed in it a lamp and a shining moon.
What's the lamp?
Prophet Noah/71:16
He made the moon a light in them and the sun a lamp.
وَجَعَلَ الْقَمَرَ ف۪يهِنَّ نُوراً وَجَعَلَ الشَّمْسَ سِرَاجاً
Prophet Jonah/10:5
He made the sun a source of light and the moon a light. He has given it phases so that you may know the number of years and reckoning. Allah has created these only for a truth. This is how He explains the verses to a people who know.
هُوَ الَّذ۪ي جَعَلَ الشَّمْسَ ضِيَٓاءً وَالْقَمَرَ نُوراً وَقَدَّرَهُ مَنَازِلَ لِتَعْلَمُوا عَدَدَ السِّن۪ينَ وَالْحِسَابَۜ مَا خَلَقَ اللّٰهُ ذٰلِكَ اِلَّا بِالْحَقِّۜ يُفَصِّلُ الْاٰيَاتِ لِقَوْمٍ يَعْلَمُونَ
Explained in Detail/41:12
So He completed them in two days as seven heavens and revealed to each heaven its special laws. And We equipped the lowest heaven with lamps and a system of protection. This is the plan of the Supreme and All-Knowing.
فَقَضٰيهُنَّ سَبْعَ سَمٰوَاتٍ ف۪ي يَوْمَيْنِ وَاَوْحٰى ف۪ي كُلِّ سَمَٓاءٍ اَمْرَهَاۜ وَزَيَّنَّا السَّمَٓاءَ الدُّنْيَا بِمَصَاب۪يحَۗ وَحِفْظاًۜ ذٰلِكَ تَقْد۪يرُ الْعَز۪يزِ الْعَل۪يمِ
The Kingdom/67:5
We adorned the lowest heavens with lamps and made them a stoning for the devils, and We prepared for them the torment of the blazing Fire.
وَلَقَدْ زَيَّنَّا السَّمَٓاءَ الدُّنْيَا بِمَصَاب۪يحَ وَجَعَلْنَاهَا رُجُوماً لِلشَّيَاط۪ينِ وَاَعْتَدْنَا لَهُمْ عَذَابَ السَّع۪يرِ
The News/78:12
And We established above you seven firm (heavens).
وَبَنَيْنَا فَوْقَـكُمْ سَبْعاً شِدَاداًۙ
