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

(51) Even thus is the grasp of thy Lord when He graspeth the townships while they are doing wrong. Lo! His grasp is painful, very strong.

(52) In truth thy Lord destroyed not the townships tyrannously while their folk were doing right.

(53) He said: Lo! in truth it saddens me that ye should take him with you, and I fear less the wolf devour him while ye are heedless of him.

(54) Deem they themselves secure from the coming on them of a pall of Allah's punishment, or the coming of the Hour suddenly while they are unaware?

(55) The thunder hymneth His praise and (so do) the angels for awe of Him. He launcheth the thunderbolts and smiteth with them whom He will while they dispute (in doubt) concerning Allah, and He is mighty in wrath.

(56) He sendeth down water from the sky, so that valleys flow according to their measure, and the flood beareth (on its surface) swelling foam - from that which they smelt in the fire in order to make ornaments and tools riseth a foam like unto it - thus Allah coineth (the similitude of) the true and the false. Then, as for the foam, it passeth away as scum upon the banks, while, as for that which is of use to mankind, it remaineth in the earth. Thus Allah coineth the similitudes.

(57) Thus We send thee (O Muhammad) unto a nation, before whom other nations have passed away, that thou mayst recite unto them that which We have inspired in thee, while they are disbelievers in the Beneficent. Say: He is my Lord; there is no Allah save Him. In Him do I put my trust and unto Him is my recourse.

(58) A similitude of the Garden which is promised unto those who keep their duty (to Allah): Underneath it rivers flow; its food is everlasting, and its shade; this is the reward of those who keep their duty, while the reward of disbelievers is the Fire.

(59) Which he sippeth but can hardly swallow, and death cometh unto him from every side while yet he cannot die, and before him is a harsh doom.

(60) And they set up rivals to Allah that they may mislead (men) from His way. Say: Enjoy life (while ye may) for lo! your journey's end will be the Fire.
