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

(1) But those who disbelieve and belie Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) - such are the dwellers of the Fire. They shall abide therein forever.

(2) And (remember) when you said, "O Musa (Moses)! We cannot endure one kind of food. So invoke your Lord for us to bring forth for us of what the earth grows, its herbs, its cucumbers, its Fum (wheat or garlic), its lentils and its onions." He said, "Would you exchange that which is better for that which is lower? Go you down to any town and you shall find what you want!" And they were covered with humiliation and misery, and they drew on themselves the Wrath of Allah. That was because they used to disbelieve the Ayat (proofs, evidence, verses, lessons, signs, revelations etc.) of Allah and killed the Prophets wrongfully. That was because they disobeyed and used to transgress the bounds (in their disobedience to Allah, i.e. commit crimes and sins).

(3) So We said: "Strike him (the dead man) with a piece of it (the cow)." Thus Allah brings the dead to life and shows you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) so that you may understand.

(4) And indeed Musa (Moses) came to you with clear proofs, yet you worshipped the calf after he left, and you were Zalimun (polytheists and wrongdoers).

(5) And they say, "None shall enter Paradise unless he be a Jew or a Christian." These are their own desires. Say (O Muhammad صلى الله عليه وسلم), "Produce your proof if you are truthful."

(6) And even if you were to bring to the people of the Scripture (Jews and Christians) all the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they would not follow your Qiblah (prayer direction), nor are you going to follow their Qiblah (prayer direction). And they will not follow each other's Qiblah (prayer direction). Verily, if you follow their desires after that which you have received of knowledge (from Allah), then indeed you will be one of the Zalimun (polytheists, wrong-doers).

(7) Verily, those who conceal the clear proofs, evidence and the guidance, which We have sent down, after We have made it clear for the people in the Book, they are the ones cursed by Allah and cursed by the cursers.

(8) Verily! In the creation of the heavens and the earth, and in the alternation of night and day, and the ships which sail through the sea with that which is of use to mankind, and the water (rain) which Allah sends down from the sky and makes the earth alive therewith after its death, and the moving (living) creatures of all kinds that He has scattered therein, and in the veering of winds and clouds which are held between the sky and the earth, are indeed Ayat (proofs, evidence, signs, etc.) for people of understanding.

(9) The month of Ramadan in which was revealed the Qur'an, a guidance for mankind and clear proofs for the guidance and the criterion (between right and wrong). So whoever of you sights (the crescent on the first night of) the month (of Ramadan i.e. is present at his home), he must observe Saum (fasts) that month, and whoever is ill or on a journey, the same number [of days which one did not observe Saum (fasts) must be made up] from other days. Allah intends for you ease, and He does not want to make things difficult for you. (He wants that you) must complete the same number (of days), and that you must magnify Allah [i.e. to say Takbir (Allahu Akbar; Allah is the Most Great] for having guided you so that you may be grateful to Him.

(10) It is made lawful for you to have sexual relations with your wives on the night of As-Saum (the fasts). They are Libas [i.e. body cover, or screen, or Sakan, (i.e. you enjoy the pleasure of living with them - as in Verse 7:189) Tafsir At-Tabari ], for you and you are the same for them. Allah knows that you used to deceive yourselves, so He turned to you (accepted your repentance) and forgave you. So now have sexual relations with them and seek that which Allah has ordained for you (offspring), and eat and drink until the white thread (light) of dawn appears to you distinct from the black thread (darkness of night), then complete your Saum (fast) till the nightfall. And do not have sexual relations with them (your wives) while you are in I'tikaf (i.e. confining oneself in a mosque for prayers and invocations leaving the worldly activities) in the mosques. These are the limits (set) by Allah, so approach them not. Thus does Allah make clear His Ayat (proofs, evidence, lessons, signs, revelations, verses, laws, legal and illegal things, Allah's set limits, orders) to mankind that they may become Al-Muttaqun (the pious - See V.2:2).
