The word(s) "light" appears 129 time(s) in 117 verse(s) in Quran in Mohsin Khan translation.

(41) Say (O Muhammad صلى الله عليه و سلم): "Who is the Lord of the heavens and the earth?" Say: "(It is) Allah." Say: "Have you then taken (for worship) Auliya' (protectors) other than Him, such as have no power either for benefit or for harm to themselves?" Say: "Is the blind equal to the one who sees? Or darkness equal to light? Or do they assign to Allah partners who created the like of His creation, so that the creation (which they made and His creation) seemed alike to them?" Say: "Allah is the Creator of all things; and He is the One, the Irresistible."

(42) Alif-Lam-Ra. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings]. (This is) a Book which We have revealed unto you (O Muhammad صلى الله عليه و سلم) in order that you might lead mankind out of darkness (of disbelief and polytheism) into light (of belief in the Oneness of Allah and Islamic Monotheism) by their Lord's Leave to the Path of the All-Mighty, the Owner of all Praise.

(43) And indeed We sent Musa (Moses) with Our Ayat (signs, proofs, and evidence) (saying): "Bring out your people from darkness into light, and remind them of the Annals of Allah. Truly, therein are Ayat (evidence, proofs and signs) for every patient, thankful (person)."

(44) And Allah has made for you in your homes an abode, and made for you out of the hides of the cattle (tents for) dwelling, which you find so light (and handy) when you travel and when you stay (in your travels); and of their wool, fur, and hair (sheep wool, camel fur, and goat hair), furnishings and articles of convenience (e.g. carpets, blankets), comfort for a while.

(45) And when those who did wrong (the disbelievers) will see the torment, then it will not be lightened unto them, nor will they be given respite.

(46) And We made their hearts firm and strong (with the light of Faith in Allah and bestowed upon them patience to bear the separation of their kith and kin and dwellings) when they stood up and said: "Our Lord is the Lord of the heavens and the earth, never shall we call upon any ilah (god) other than Him; if we did, we should indeed have uttered an enormity in disbelief.

(47) And you would have thought them awake, whereas they were asleep. And We turned them on their right and on their left sides, and their dog stretching forth his two forelegs at the entrance [of the Cave or in the space near to the entrance of the Cave (as a guard at the gate)]. Had you looked at them, you would certainly have turned back from them in flight, and would certainly have been filled with awe of them.

(48) And indeed We granted to Musa (Moses) and Harun (Aaron) the criterion (of right and wrong), and a shining light [i.e. the Taurat (Torah)] and a Reminder for Al-Muttaqun (the pious - See V.2:2).

(49) They shall not hear the slightest sound of it (Hell), while they abide in that which their ownselves desire.

(50) And among men is he who disputes about Allah, without knowledge or guidance, or a Book giving light (from Allah),
