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

(71) And We have not sent down the Book (the Qur'an) to you (O Muhammad صلى الله عليه و سلم), except that you may explain clearly unto them those things in which they differ, and (as) a guidance and a mercy for a folk who believe.

(72) And Allah sends down water (rain) from the sky, then He revives the earth therewith after its death. Verily, in this is a sign (clear proof) for people who listen (obey Allah).

(73) Do they not see the birds held (flying) in the midst of the sky? None holds them but Allah [none gave them the ability to fly but Allah]. Verily, in this are clear Ayat (proofs and signs) for people who believe (in the Oneness of Allah).

(74) Then, if they turn away, your duty (O Muhammad صلى الله عليه و سلم) is only to convey (the Message) in a clear way.

(75) And be not like her who undoes the thread which she has spun, after it has become strong, by taking your oaths as a means of deception among yourselves, lest a nation should be more numerous than another nation. Allah only tests you by this [i.e who obeys Allah and fulfils Allah's Covenant and who disobeys Allah and breaks Allah's Covenant]. And on the Day of Resurrection, He will certainly make clear to you that wherein you used to differ [i.e. a believer confesses and believes in the Oneness of Allah and in the Prophethood of Prophet Muhammad صلى الله عليه و سلم which the disbeliever denies and that is their difference amongst them in the life of this world] .

(76) And indeed We know that they (polytheists and pagans) say: "It is only a human being who teaches him (Muhammad صلى الله عليه و سلم)." The tongue of the man they refer to is foreign, while this (the Qur'an) is a clear Arabic tongue.

(77) And nothing stops Us from sending the Ayat (proofs, evidence, signs) but that the people of old denied them. And We sent the she-camel to Thamud as a clear sign, but they did her wrong. And We sent not the signs except to warn, and to make them afraid (of destruction).

(78) And indeed We gave Musa (Moses) nine clear signs. Ask then the Children of Israel, when he came to them, then Fir'aun (Pharaoh) said to him: "O Musa (Moses)! I think you are indeed bewitched."

(79) [Musa (Moses)] said: "Verily, you know that these signs have been sent down by none but the Lord of the heavens and the earth (as clear evidence i.e. proofs of Allah's Oneness and His Omnipotence.). And I think you are, indeed, O Fir'aun (Pharaoh) doomed to destruction (away from all good)!"

(80) "These our people have taken for worship alihah (gods) other than Him (Allah). Why do they not bring for them a clear authority? And who does more wrong than he who invents a lie against Allah.
