The word(s) "light" appears 125 time(s) in 114 verse(s) in Quran in Muhammad Pickthal translation.

(21) And We caused Jesus, son of Mary, to follow in their footsteps, confirming that which was (revealed) before him in the Torah, and We bestowed on him the Gospel wherein is guidance and a light, confirming that which was (revealed) before it in the Torah - a guidance and an admonition unto those who ward off (evil).

(22) Shall I tell thee of a worse (case) than theirs for retribution with Allah? (Worse is the case of him) whom Allah hath cursed, him on whom His wrath hath fallen and of whose sort Allah hath turned some to apes and swine, and who serveth idols. Such are in worse plight and further astray from the plain road.

(23) The Jews say: Allah's hand is fettered. Their hands are fettered and they are accursed for saying so. Nay, but both His hands are spread out wide in bounty. He bestoweth as He will. That which hath been revealed unto thee from thy Lord is certain to increase the contumacy and disbelief of many of them, and We have cast among them enmity and hatred till the Day of Resurrection. As often as they light a fire for war, Allah extinguisheth it. Their effort is for corruption in the land, and Allah loveth not corrupters.

(24) If only the People of the Scripture would believe and ward off (evil), surely We should remit their sins from them and surely We should bring them into Gardens of Delight.

(25) Praise be to Allah, Who hath created the heavens and the earth, and hath appointed darkness and light. Yet those who disbelieve ascribe rivals unto their Lord.

(26) And they measure not the power of Allah its true measure when they say: Allah hath naught revealed unto a human being. Say (unto the Jews who speak thus): Who revealed the Book which Moses brought, a light and guidance for mankind, which ye have put on parchments which ye show, but ye hide much (thereof), and (by which) ye were taught that which ye knew not yourselves nor (did) your fathers (know it)? Say: Allah. Then leave them to their play of cavilling.

(27) Is he who was dead and We have raised him unto life, and set for him a light wherein he walketh among men, as him whose similitude is in utter darkness whence he cannot emerge? Thus is their conduct made fairseeming for the disbelievers.

(28) And as for those whose scale is light: those are they who lose their souls because they used to wrong Our revelations.

(29) Then changed We the evil plight for good till they grew affluent and said: Tribulation and distress did touch our fathers. Then We seized them unawares, when they perceived not.

(30) Those who follow the messenger, the Prophet who can neither read nor write, whom they will find described in the Torah and the Gospel (which are) with them. He will enjoin on them that which is right and forbid them that which is wrong. He will make lawful for them all good things and prohibit for them only the foul; and he will relieve them of their burden and the fetters that they used to wear. Then those who believe in him, and honour him, and help him, and follow the light which is sent down with him: they are the successful.
