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

(121) And (remember) when We said to the angels: "Prostrate yourselves unto Adam." So they prostrated themselves except Iblis (Satan). He was one of the jinn; he disobeyed the Command of his Lord. Will you then take him (Iblis) and his offspring as protectors and helpers rather than Me while they are enemies to you? What an evil is the exchange for the Zalimun (polytheists, and wrong-doers).

(122) "Those whose efforts have been wasted in this life while they thought that they were acquiring good by their deeds.

(123) (It was said to his son): "O Yahya (John)! Hold fast the Scripture [the Taurat (Torah)]." And We gave him wisdom while yet a child.

(124) And warn them (O Muhammad صلى الله عليه وسلم) of the Day of grief and regrets, when the case has been decided, while (now) they are in a state of carelessness, and they believe not .

(125) Does not man remember that We created him before, while he was nothing?

(126) And he who works deeds of righteousness, while he is a believer (in Islamic Monotheism), then he will have no fear of injustice, nor of any curtailment (of his reward).

(127) He will say: "O my Lord! Why have you raised me up blind, while I had sight (before)."

(128) Draws near for mankind their reckoning, while they turn away in heedlessness.

(129) Comes not unto them an admonition (a chapter of the Qur'an) from their Lord as a recent revelation but they listen to it while they play

(130) With their hearts occupied (with evil things). Those who do wrong, conceal their private counsels, (saying): "Is this (Muhammad صلى الله عليه وسلم) more than a human being like you? Will you submit to magic while you see it?"
