God is the source of (visible and invisible) light of the universe!

Verses 35-36 of Chapter 24

Allah is the Light of the heavens and the earth. The Parable of His Light is as if there were a Niche and within it a Lamp: the Lamp enclosed in Glass: the glass as it were a brilliant star: Lit from a blessed Tree, an Olive, neither of the east nor of the west, whose oil is well-nigh luminous, though fire scarce touched it: Light upon Light! Allah doth guide whom He will to His Light: Allah doth set forth Parables for men: and Allah doth know all things.

Verses 7-9 of Chapter 27

(Remember) when Musa said to his household: "Verily, I have seen a fire; I will bring you from there some information, or I will bring you a burning ember, that you may warm yourselves.'' But when he came to it, he was called: "Blessed is whosoever is in the fire, and whosoever is round about it! And glorified be Allah, the Lord of all that exists.'' "O Musa! Verily, it is I, Allah, the All-Mighty, the All-Wise.''

Verses 68-69 of Chapter 39

And the trumpet shall be blown, so all those that are in the heavens and all those that are in the earth shall swoon, except such as Allah please; then it shall be blown again, then lo! they shall stand up awaiting. And the earth shall beam with the light of its Lord, and the Book shall be laid down, and the prophets and the witnesses shall be brought up, and judgment shall be given between them with justice, and they shall not be dealt with unjustly.
