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

(121) Say: "Have ye seen (these) 'Partners' of yours whom ye call upon besides Allah? Show Me what it is they have created in the (wide) earth. Or have they a share in the heavens? Or have We given them a Book from which they (can derive) clear (evidence)?- Nay, the wrong-doers promise each other nothing but delusions.

(122) Verily We shall give life to the dead, and We record that which they send before and that which they leave behind, and of all things have We taken account in a clear Book (of evidence).

(123) "And our duty is only to proclaim the clear Message."

(124) We have not instructed the (Prophet) in Poetry, nor is it meet for him: this is no less than a Message and a Qur'an making things clear:

(125) Round will be passed to them a Cup from a clear-flowing fountain,

(126) And We gave them the Book which helps to make things clear;

(127) That was because there came to them their messengers with clear (Signs), but they rejected them: So Allah called them to account: for He is Full of Strength, Strict in Punishment.

(128) A believer, a man from among the people of Pharaoh, who had concealed his faith, said: "Will ye slay a man because he says, 'My Lord is Allah'?- when he has indeed come to you with clear (Signs) from your Lord? and if he be a liar, on him is (the sin of) his lie: but, if he is telling the Truth, then will fall on you something of the (calamity) of which he warns you: Truly Allah guides not one who transgresses and lies!

(129) "And to you there came Joseph in times gone by, with clear Signs, but ye ceased not to doubt of the (Mission) for which he had come: At length, when he died, ye said: 'No messenger will Allah send after him.' thus doth Allah leave to stray such as transgress and live in doubt,-

(130) They will say: "Did there not come to you your messengers with clear Signs?" They will say, "Yes". They will reply, "Then pray (as ye like)! But the prayer of those without Faith is nothing but (futile wandering) in (mazes of) error!"
