The word(s) "witness" appears 123 time(s) in 99 verse(s) in Quran in Mohsin Khan translation.

(91) When the hypocrites come to you (O Muhammad صلى الله عليه وسلم), they say: "We bear witness that you are indeed the Messenger of Allah." Allah knows that you are indeed His Messenger, and Allah bears witness that the hypocrites are liars indeed.

(92) Then when they are about to attain their term appointed, either take them back in a good manner or part with them in a good manner. And take as witness two just persons from among you (Muslims). And establish the testimony for Allah. That will be an admonition given to him who believes in Allah and the Last Day. And whosoever fears Allah and keeps his duty to Him, He will make a way for him to get out (from every difficulty).

(93) Verily, We have sent to you (O men) a Messenger (Muhammad صلى الله عليه وسلم) to be a witness over you, as We did send a Messenger [Musa (Moses)] to Fir'aun (Pharaoh).

(94) Nay! Man will be a witness against himself [as his body parts (skin, hands, legs, etc.) will speak about his deeds],

(95) To which bear witness those nearest (to Allah, i.e. the angels).

(96) And by the witnessing day (i.e. Friday), and by the witnessed day [i.e. the day of 'Arafat (Hajj) the ninth of Dhul-Hijjah];

(97) And they witnessed what they were doing against the believers (i.e. burning them).

(98) To Whom belongs the dominion of the heavens and the earth! And Allah is witness over everything.

(99) And to that he bears witness (by his deeds).
