The word(s) "while" appears 135 time(s) in 132 verse(s) in Quran in Muhammad Pickthal translation.

(11) Of those messengers, some of whom We have caused to excel others, and of whom there are some unto whom Allah spake, while some of them He exalted (above others) in degree; and We gave Jesus, son of Mary, clear proofs (of Allah's Sovereignty) and We supported him with the holy Spirit. And if Allah had so wiled it, those who followed after them would not have fought one with another after the clear proofs had come unto them. But they differed, some of them believing and some disbelieving. And if Allah had so willed it, they would not have fought one with another; but Allah doeth what He will.

(12) Allah! There is no deity save Him, the Alive, the Eternal. Neither slumber nor sleep overtaketh Him. Unto Him belongeth whatsoever is in the heavens and whatsoever is in the earth. Who is he that intercedeth with Him save by His leave? He knoweth that which is in front of them and that which is behind them, while they encompass nothing of His knowledge save what He will. His throne includeth the heavens and the earth, and He is never weary of preserving them. He is the Sublime, the Tremendous.

(13) Or deemed ye that ye would enter paradise while yet Allah knoweth not those of you who really strive, nor knoweth those (of you) who are steadfast?

(14) When ye climbed (the hill) and paid no heed to anyone, while the messenger, in your rear, was calling you (to fight). Therefor He rewarded you grief for (his) grief, that (He might teach) you not to sorrow either for that which ye missed or for that which befell you. Allah is Informed of what ye do.

(15) Then, after grief, He sent down security for you. As slumber did it overcome a party of you, while (the other) party, who were anxious on their own account, thought wrongly of Allah, the thought of ignorance. They said: Have we any part in the cause? Say (O Muhammad): The cause belongeth wholly to Allah. They hide within themselves (a thought) which they reveal not unto thee, saying: Had we had any part in the cause we should not have been slain here. Say: Even though ye had been in your houses, those appointed to be slain would have gone forth to the places where they were to lie. (All this hath been) in order that Allah might try what is in your breasts and prove what is in your hearts. Allah is Aware of what is hidden in the breasts (of men).

(16) Those who, while they sat at home, said of their brethren (who were fighting for the cause of Allah): If they had been guided by us they would not have been slain. Say (unto them, O Muhammad): Then avert death from yourselves if ye are truthful.

(17) The forgiveness is not for those who do ill-deeds until, when death attendeth upon one of them, he saith: Lo! I repent now; nor yet for those who die while they are disbelievers. For such We have prepared a painful doom.

(18) Hast thou not seen those unto whom it was said: Withhold your hands, establish worship and pay the poordue, but when fighting was prescribed for them behold! a party of them fear mankind even as their fear of Allah or with greater fear, and say: Our Lord! Why hast Thou ordained fighting for us? If only Thou wouldst give us respite yet a while! Say (unto them, O Muhammad): The comfort of this world is scant; the Hereafter will be better for him who wardeth off (evil); and ye will not be wronged the down upon a date-stone.

(19) Lo! as for those whom the angels take (in death) while they wrong themselves, (the angels) will ask: In what were ye engaged? They will say: We were oppressed in the land. (The angels) will say: Was not Allah's earth spacious that ye could have migrated therein? As for such, their habitation will be hell, an evil journey's end;

(20) Who is better in religion than he who surrendereth his purpose to Allah while doing good (to men) and followeth the tradition of Abraham, the upright? Allah (Himself) chose Abraham for friend.
