The word(s) "witness" appears 132 time(s) in 112 verse(s) in Quran in Abdullah Yusuf Ali translation.

(71) O Prophet! Truly We have sent thee as a witness, a Bearer of Glad Tidings, and Warner,-

(72) There is no blame (on these ladies if they appear) before their fathers or their sons, their brothers, or their brother's sons, or their sisters' sons, or their women, or the (slaves) whom their right hands possess. And, (ladies), fear Allah; for Allah is witness to all things.

(73) Say: "No reward do I ask of you: it is (all) in your interest: my reward is only due from Allah: And He is witness to all things."

(74) That Day shall We set a seal on their mouths. But their hands will speak to us, and their feet bear witness, to all that they did.

(75) "Who used to say, 'what! art thou amongst those who bear witness to the Truth (of the Message)?

(76) Or that We created the angels female, and they are witnesses (thereto)?

(77) And the Earth will shine with the Glory of its Lord: the Record (of Deeds) will be placed (open); the prophets and the witnesses will be brought forward and a just decision pronounced between them; and they will not be wronged (in the least).

(78) We will, without doubt, help our messengers and those who believe, (both) in this world's life and on the Day when the witnesses will stand forth,-

(79) At length, when they reach the (Fire), their hearing, their sight, and their skins will bear witness against them, as to (all) their deeds.

(80) They will say to their skins: "Why bear ye witness against us?" They will say: "Allah hath given us speech,- (He) Who giveth speech to everything: He created you for the first time, and unto Him were ye to return.
