The word(s) "proof" appears 241 time(s) in 235 verse(s) in Quran in Mohsin Khan translation.

(161) Verily, in this is an Ayah (proof or sign), yet most of them (polytheists, pagans who do not believe in Resurrection) are not believers.

(162) Verily in this is indeed a sign (or a proof), yet most of them are not believers.

(163) But when Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) came to them, clear to see, they said: "This is a manifest magic."

(164) Is not He (better than your so-called gods) Who originates creation, and shall thereafter repeat it, and Who provides for you from heaven and earth? Is there any ilah (god) with Allah? Say: "Bring forth your proofs, if you are truthful."

(165) Nor can you lead the blind out of their error. You can only make to hear those who believe in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and who have submitted (themselves to Allah in Islam as Muslims).

(166) And (remember) the Day when We shall gather out of every nation a troop of those who denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and (then) they (all) shall be driven (to the place of reckoning),

(167) Till, when they come (before their Lord at the place of reckoning), He will say: "Did you deny My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) whereas you comprehended them not by knowledge (of their truth or falsehood), or what (else) was it that you used to do?"

(168) See they not that We have made the night for them to rest therein, and the day sight-giving? Verily, in this are Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) for the people who believe.

(169) "Put your hand in your bosom, it will come forth white without a disease; and draw your hand close to your side to be free from the fear (which you suffered from the snake, and also your hand will return to its original state). These are two Burhans (signs, miracles, evidence, proofs) from your Lord to Fir'aun (Pharaoh) and his chiefs. Verily, they are the people who are Fasiqun (rebellious, disobedient to Allah).

(170) Allah said: "We will strengthen your arm through your brother, and give you both power, so they shall not be able to harm you: with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), you two as well as those who follow you will be the victors."
