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

(91) And there will come forth every soul: with each will be an (angel) to drive, and an (angel) to bear witness.

(92) Verily in this is a Message for any that has a heart and understanding or who gives ear and earnestly witnesses (the truth).

(93) It is We Who have created you: why will ye not witness the Truth?

(94) Furthermore I call to witness the setting of the Stars,-

(95) And those who believe in Allah and His messengers- they are the Sincere (lovers of Truth), and the witnesses (who testify), in the eyes of their Lord: They shall have their Reward and their Light. But those who reject Allah and deny Our Signs,- they are the Companions of Hell-Fire.

(96) On the Day that Allah will raise them all up (again) and show them the Truth (and meaning) of their conduct. Allah has reckoned its (value), though they may have forgotten it, for Allah is witness to all things.

(97) Hast thou not observed the Hypocrites say to their misbelieving brethren among the People of the Book? - "If ye are expelled, we too will go out with you, and we will never hearken to any one in your affair; and if ye are attacked (in fight) we will help you". But Allah is witness that they are indeed liars.

(98) When the Hypocrites come to thee, they say, "We bear witness that thou art indeed the Messenger of Allah." Yea, Allah knoweth that thou art indeed His Messenger, and Allah beareth witness that the Hypocrites are indeed liars.

(99) Thus when they fulfil their term appointed, either take them back on equitable terms or part with them on equitable terms; and take for witness two persons from among you, endued with justice, and establish the evidence (as) before Allah. Such is the admonition given to him who believes in Allah and the Last Day. And for those who fear Allah, He (ever) prepares a way out,

(100) So I do call to witness what ye see,
