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

(131) And indeed We have sent down for you Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) that make things plain, and the example of those who passed away before you, and an admonition for those who are Al-Muttaqun (the pious - See V.2:2).

(132) We have indeed sent down (in this Qur'an) manifest Ayat (proofs, evidence, verses, lessons, signs, revelations, lawful and unlawful things, and the set boundaries of Islamic religion, etc. that make things clear showing the Right Path of Allah). And Allah guides whom He wills to the Straight Path (i.e. to Allah's religion of Islamic Monotheism).

(133) O you who believe! Let your slaves and slave-girls, and those among you who have not come to the age of puberty ask your permission (before they come to your presence) on three occasions: before Fajr (morning) Salat (prayer), and while you put off your clothes for the noonday (rest), and after the 'Isha' (late-night) Salat (prayer). (These) three times are of privacy for you; other than these times there is no sin on you or on them to move about, attending to each other. Thus Allah makes clear the Ayat (the Verses of this Qur'an, showing proofs for the legal aspects of permission for visits) to you. And Allah is All-Knowing, All-Wise.

(134) And We said: "Go you both to the people who have denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.)." Then We destroyed them with utter destruction.

(135) And for each (of them) We put forward examples (as proofs and lessons), and each (of them) We brought to utter ruin (because of their disbelief and evil deeds).

(136) And those who, when they are reminded of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord, fall not deaf and blind thereat.

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

(138) 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."

(139) 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).

(140) 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),
