The word(s) "light" appears 146 time(s) in 131 verse(s) in Quran in Abdullah Yusuf Ali translation.

(91) So He completed them as seven firmaments in two Days, and He assigned to each heaven its duty and command. And We adorned the lower heaven with lights, and (provided it) with guard. Such is the Decree of (Him) the Exalted in Might, Full of Knowledge.

(92) But if they turn away, say thou: "I have warned you of a stunning Punishment (as of thunder and lightning) like that which (overtook) the 'Ad and the Thamud!"

(93) And thus have We, by Our Command, sent inspiration to thee: thou knewest not (before) what was Revelation, and what was Faith; but We have made the (Qur'an) a light, wherewith We guide such of Our servants as We will; and verily thou dost guide (men) to the Straight Way,-

(94) To them will be passed round, dishes and goblets of gold: there will be there all that the souls could desire, all that their eyes could delight in: and ye shall abide therein (for eye).

(95) Nowise will the (Punishment) be lightened for them, and in despair will they be there overwhelmed.

(96) And wealth (and conveniences of life), wherein they had taken such delight!

(97) But to those who receive Guidance, He increases the (light of) Guidance, and bestows on them their Piety and Restraint (from evil).

(98) Or do those in whose hearts is a disease, think that Allah will not bring to light all their rancour?

(99) Verily those who plight their fealty to thee do no less than plight their fealty to Allah: the Hand of Allah is over their hands: then any one who violates his oath, does so to the harm of his own soul, and any one who fulfils what he has covenanted with Allah,- Allah will soon grant him a great Reward.

(100) Muhammad is the messenger of Allah; and those who are with him are strong against Unbelievers, (but) compassionate amongst each other. Thou wilt see them bow and prostrate themselves (in prayer), seeking Grace from Allah and (His) Good Pleasure. On their faces are their marks, (being) the traces of their prostration. This is their similitude in the Taurat; and their similitude in the Gospel is: like a seed which sends forth its blade, then makes it strong; it then becomes thick, and it stands on its own stem, (filling) the sowers with wonder and delight. As a result, it fills the Unbelievers with rage at them. Allah has promised those among them who believe and do righteous deeds forgiveness, and a great Reward.
