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

(211) And indeed We did send Musa (Moses) with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) to Fir'aun (Pharaoh) and his chiefs (inviting them to Allah's religion of Islam) He said: "Verily, I am a Messenger of the Lord of the 'Alamin (mankind, jinn and all that exists)."

(212) But when he came to them with Our Ayat (proofs, evidence, verses, lessons, signs, revelations) behold, they laughed at them.

(213) And when 'Îsa (Jesus) came with (Our) clear proofs, he said: "I have come to you with Al-Hikmah (Prophethood), and in order to make clear to you some of the (points) in which you differ. Therefore fear Allah and obey me.

(214) (You) who believed in Our Ayat (proofs, verses, lessons, signs, revelations, etc.) and were Muslims (i.e. who submit totally to Allah's Will, and believe in the Oneness of Allah - Islamic Monotheism).

(215) These are the Ayat (proofs, evidence, verses, lessons, revelations, etc.) of Allah, which We recite to you (O Muhammad صلى الله عليه و سلم) with truth. Then in which speech after Allah and His Ayat will they believe?

(216) This (Qur'an) is a guidance. And those who disbelieve in the Ayat (proofs, evidence, verses, lessons, signs, revelations) of their Lord, for them there is a painful torment of Rijz (a severe kind of punishment).

(217) And gave them clear proofs in matters [by revealing to them the Taurat (Torah)]. And they differed not until after the knowledge came to them, through envy among themselves. Verily, Your Lord will judge between them on the Day of Resurrection about that wherein they used to differ.

(218) And indeed We had firmly established them with that wherewith We have not established you (O Quraish)! And We had assigned them the (faculties of) hearing (ears), seeing (eyes), and hearts; but their hearing (ears), seeing (eyes), and their hearts availed them nothing since they used to deny the Ayat (Allah's Prophets and their Prophethood, proofs, evidence, verses, signs, revelations) of Allah, and they were completely encircled by that which they used to mock at!

(219) And indeed We have destroyed towns (populations) round about you, and We have (repeatedly) shown (them) the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) in various ways that they might return (to the truth and believe in the Oneness of Allah - Islamic Monotheism).

(220) Is he who is on a clear proof from his Lord, like those for whom their evil deeds that they do are beautified for them, while they follow their own lusts (evil desires)?
