The word(s) "while" appears 218 time(s) in 214 verse(s) in Quran in Mohsin Khan translation.

(51) "Never did I say to them aught except what You (Allah) did command me to say: 'Worship Allah, my Lord and your Lord.' And I was a witness over them while I dwelt amongst them, but when You took me up, You were the Watcher over them; and You are a Witness to all things. (This is a great admonition and warning to the Christians of the whole world).

(52) They indeed are losers who denied their Meeting with Allah, until all of a sudden, the Hour (signs of death) is on them, and they say: "Alas for us that we gave no thought to it," while they will bear their burdens on their backs; and evil indeed are the burdens that they will bear!

(53) His people disputed with him. He said: "Do you dispute with me concerning Allah while He has guided me, and I fear not those whom you associate with Him (Allah) in worship. (Nothing can happen to me) except when my Lord (Allah) wills something. My Lord comprehends in His Knowledge all things. Will you not then remember?

(54) "And how should I fear those whom you associate in worship with Allah (though they can neither benefit nor harm), while you fear not that you have joined in worship with Allah things for which He has not sent down to you any authority. (So) which of the two parties has more right to be in security? If you but know."

(55) And who can be more unjust than he who invents a lie against Allah, or says: "A revelation has come to me" whereas no revelation has come to him in anything ; and who says, "I will reveal the like of what Allah has revealed." And if you could but see when the Zalimun (polytheists and wrong-doers) are in the agonies of death, while the angels are stretching forth their hands (saying): "Deliver your souls! This day you shall be recompensed with the torment of degradation because of what you used to utter against Allah other than the truth. And you used to reject His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) with disrespect! "

(56) [Say (O Muhammad صلى الله عليه وسلم)] "Shall I seek a judge other than Allah while it is He Who has sent down unto you the Book (the Qur'an), explained in detail." Those unto whom We gave the Scripture [the Taurat (Torah) and the Injeel (Gospel)] know that it is revealed from your Lord in truth. So be not you of those who doubt.

(57) So eat of that (meat) on which Allah's Name has been pronounced (while slaughtering the animal), if you are believers in His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(58) And why should you not eat of that (meat) on which Allah's Name has been pronounced (at the time of slaughtering the animal), while He has explained to you in detail what is forbidden to you, except under compulsion of necessity? And surely many do lead (mankind) astray by their own desires through lack of knowledge. Certainly your Lord knows best the transgressors.

(59) This is because your Lord would not destroy the (populations of) towns for their wrong-doing (i.e. associating others in worship along with Allah) while their people were unaware (so the Messengers were sent).

(60) And they assign to Allah a share of the tilth and cattle which He has created, and they say: "This is for Allah according to their claim, and this is for our (Allah's so-called) partners." But the share of their (Allah's so-called) "partners" reaches not Allah, while the share of Allah reaches their (Allah's so-called) "partners"! Evil is the way they judge!
