The word(s) "clear" appears 174 time(s) in 168 verse(s) in Quran in Abdullah Yusuf Ali translation.

(141) By the Book that makes things clear;-

(142) How shall the message be (effectual) for them, seeing that a Messenger explaining things clearly has (already) come to them,-

(143) And We granted them clear Signs in affairs (of Religion): it was only after knowledge had been granted to them that they fell into schisms, through insolent envy among themselves. Verily thy Lord will judge between them on the Day of Judgment as to those matters in which they set up differences.

(144) These are clear evidences to men and a Guidance and Mercy to those of assured Faith.

(145) And when Our clear Signs are rehearsed to them their argument is nothing but this: They say, "Bring (back) our forefathers, if what ye say is true!"

(146) When Our clear Signs are rehearsed to them, the Unbelievers say, of the Truth when it comes to them: "This is evident sorcery!"

(147) Say: "I am no bringer of new-fangled doctrine among the messengers, nor do I know what will be done with me or with you. I follow but that which is revealed to me by inspiration; I am but a Warner open and clear."

(148) Is then one who is on a clear (Path) from his Lord, no better than one to whom the evil of his conduct seems pleasing, and such as follow their own lusts?

(149) (Here is) a Parable of the Garden which the righteous are promised: in it are rivers of water incorruptible; rivers of milk of which the taste never changes; rivers of wine, a joy to those who drink; and rivers of honey pure and clear. In it there are for them all kinds of fruits; and Grace from their Lord. (Can those in such Bliss) be compared to such as shall dwell for ever in the Fire, and be given, to drink, boiling water, so that it cuts up their bowels (to pieces)?

(150) Those who turn back as apostates after Guidance was clearly shown to them,- the Evil One has instigated them and busied them up with false hopes.
