The word(s) "proofs" appears 207 time(s) in 204 verse(s) in Quran in Mohsin Khan translation.

(81) Verily, those who hope not for their meeting with Us, but are pleased and satisfied with the life of the present world, and those who are heedless of Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.),

(82) And indeed, We destroyed generations before you when they did wrong, while their Messengers came to them with clear proofs, but they were not such as to believe! Thus do We requite the people who are Mujrimun (disbelievers, polytheists, sinners, criminals).

(83) So who does more wrong than he who forges a lie against Allah or denies His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.)? Surely, the Mujrimun (criminals, sinners, disbelievers and polytheists) will never be successful!

(84) And when We let mankind taste mercy after some adversity has afflicted them, behold! they take to plotting against Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.)! Say: "Allah is more Swift in planning!" Certainly, Our Messengers (angels) record all of that which you plot.

(85) Verily, the likeness of (this) worldly life is as the water (rain) which We send down from the sky; so by it arises the intermingled produce of the earth of which men and cattle eat: until when the earth is clad in its adornments and is beautified, and its people think that they have all the powers of disposal over it, Our Command reaches it by night or by day and We make it like a clean-mown harvest, as if it had not flourished yesterday! Thus do We explain the Ayat (proofs, evidence, verses, lessons, signs, revelations, laws, etc.) in detail for the people who reflect.

(86) He it is Who has appointed for you the night that you may rest therein, and the day to make things visible (to you). Verily, in this are Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) for a people who listen (i.e. those who think deeply).

(87) (A brief) enjoyment in this world! - and then unto Us will be their return, then We shall make them taste the severest torment because they used to disbelieve [in Allah, belie His Messengers, deny and challenge His Ayat (proofs, signs, verses, etc.)].

(88) And recite to them the news of Nuh (Noah). When he said to his people: "O my people, if my stay (with you), and my reminding (you) of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah is hard on you, then I put my trust in Allah. So devise your plot, you and your partners, and let not your plot be in doubt for you. Then pass your sentence on me and give me no respite.

(89) They denied him, but We delivered him, and those with him in the ship, and We made them generations replacing one after another, while We drowned those who belied Our Ayat (proofs, evidence, lessons, signs, revelations, etc.). Then see what was the end of those who were warned.

(90) Then after him We sent Messengers to their people. They brought them clear proofs, but they would not believe what they had already rejected beforehand. Thus We seal the hearts of the transgressors (those who disbelieve in the Oneness of Allah and disobey Him).
