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

(81) "Ye did not seek to hide yourselves, lest your hearing, your sight, and your skins should bear witness against you! But ye did think that Allah knew not many of the things that ye used to do!

(82) To Him is referred the Knowledge of the Hour (of Judgment: He knows all): No date-fruit comes out of its sheath, nor does a female conceive (within her womb) nor bring forth the Day that (Allah) will propound to them the (question), "Where are the partners (ye attributed to Me?" They will say, "We do assure thee not one of us can bear witness!"

(83) Soon will We show them our Signs in the (furthest) regions (of the earth), and in their own souls, until it becomes manifest to them that this is the Truth. Is it not enough that thy Lord doth witness all things?

(84) And they make into females angels who themselves serve Allah. Did they witness their creation? Their evidence will be recorded, and they will be called to account!

(85) And Pharaoh proclaimed among his people, saying: "O my people! Does not the dominion of Egypt belong to me, (witness) these streams flowing underneath my (palace)? What! see ye not then?

(86) And those whom they invoke besides Allah have no power of intercession;- only he who bears witness to the Truth, and they know (him).

(87) Or do they say, "He has forged it"? Say: "Had I forged it, then can ye obtain no single (blessing) for me from Allah. He knows best of that whereof ye talk (so glibly)! Enough is He for a witness between me and you! And he is Oft-Forgiving, Most Merciful."

(88) Say: "See ye? If (this teaching) be from Allah, and ye reject it, and a witness from among the Children of Israel testifies to its similarity (with earlier scripture), and has believed while ye are arrogant, (how unjust ye are!) truly, Allah guides not a people unjust."

(89) We have truly sent thee as a witness, as a bringer of Glad Tidings, and as a Warner:

(90) It is He Who has sent His Messenger with Guidance and the Religion of Truth, to proclaim it over all religion: and enough is Allah for a witness.
