The word(s) "clear" appears 159 time(s) in 147 verse(s) in Quran in Mohsin Khan translation.

(61) "Go with this shirt of mine, and cast it over the face of my father, he will become clear-sighted, and bring me all your family."

(62) Then, when the bearer of the glad tidings arrived, he cast it (the shirt) over his face, and he became clear-sighted. He said: "Did I not say to you, 'I know from Allah that which you know not.'"

(63) And We sent not a Messenger except with the language of his people, in order that he might make (the Message) clear for them. Then Allah misleads whom He wills and guides whom He wills. And He is the All-Mighty, the All-Wise.

(64) Has not the news reached you, of those before you, the people of Nuh (Noah), and 'Ad, and Thamud? And those after them? None knows them but Allah. To them came their Messengers with clear proofs, but they put their hands in their mouths (biting them from anger) and said: "Verily, we disbelieve in that with which you have been sent, and we are really in grave doubt as to that to which you invite us (i.e. Islamic Monotheism)."

(65) Their Messengers said: "What! Can there be a doubt about Allah, the Creator of the heavens and the earth? He calls you (to Monotheism and to be obedient to Allah) that He may forgive you of your sins and give you respite for a term appointed." They said: "You are no more than human beings like us! You wish to turn us away from what our fathers used to worship. Then bring us a clear authority (i.e. a clear proof of what you say)."

(66) "And you dwelt in the dwellings of men who wronged themselves, and it was clear to you how We had dealt with them. And We put forth (many) parables for you."

(67) This (Qur'an) is a Message for mankind (and a clear proof against them), in order that they may be warned thereby, and that they may know that He is the only One Ilah (God - Allah) - (none has the right to be worshipped but Allah) - and that men of understanding may take heed.

(68) Except him (devil) who steals the hearing then he is pursued by a clear flaming fire.

(69) And those who joined others in worship with Allah said: "If Allah had so willed, neither we nor our fathers would have worshipped aught but Him, nor would we have forbidden anything without (Command from) Him." So did those before them. Then! Are the Messengers charged with anything but to convey clearly the Message?

(70) With clear signs and Books (We sent the Messengers). And We have also sent down unto you (O Muhammad صلى الله عليه و سلم) the Dhikr [reminder and the advice (i.e. the Qur'an)], that you may explain clearly to men what is sent down to them, and that they may give thought.
