The word(s) "light" appears 103 time(s) in 90 verse(s) in Quran in Muhammad Habib Shakir translation.

(41) And when those who are unjust shall see the chastisement, it shall not be lightened for them, nor shall they be respited.

(42) And you might think them awake while they were asleep and We turned them about to the right and to the left, while their dog (lay) outstretching its paws at the entrance; if you looked at them you would certainly turn back from them in flight, and you would certainly be filled with awe because of them.

(43) Say: As for him who remains in error, the Beneficent Allah will surely prolong his length of days, until they see what they were threatened with, either the punishment or the hour; then they shall know who is in more evil plight and weaker in forces

(44) And certainly We gave to Musa and Haroun the Furqan and a light and a reminder for those who would guard (against evil).

(45) And say: O my Lord! cause me to disembark a blessed alighting, and Thou art the best to cause to alight.

(46) And as for him whose good deeds are light, these are they who shall have lost their souls, abiding in hell

(47) Allah is the light of the heavens and the earth; a likeness of His light is as a niche in which is a lamp, the lamp is in a glass, (and) the glass is as it were a brightly shining star, lit from a blessed olive-tree, neither eastern nor western, the oil whereof almost gives light though fire touch it not-- light upon light-- Allah guides to His light whom He pleases, and Allah sets forth parables for men, and Allah is Cognizant of all things.

(48) Or like utter darkness in the deep sea: there covers it a wave above which is another wave, above which is a cloud, (layers of) utter darkness one above another; when he holds out his hand, he is almost unable to see it; and to whomsoever Allah does not give light, he has no light.

(49) Do you not see that Allah drives along the clouds, then gathers them together, then piles them up, so that you see the rain coming forth from their midst? And He sends down of the clouds that are (like) mountains wherein is hail, afflicting therewith whom He pleases and turning it away from whom He pleases; the flash of His lightning almost takes away the sight.

(50) (As for) those who shall be gathered upon their faces to hell, they are in a worse plight and straying farther away from the path.
