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

(41) So let not their riches nor their children please thee (O Muhammad). Allah thereby intendeth but to punish them in the life of the world and that their souls shall pass away while they are disbelievers.

(42) Even as those before you who were mightier than you in strength, and more affluent than you in wealth and children. They enjoyed their lot awhile, so ye enjoy your lot awhile even as those before you did enjoy their lot awhile. And ye prate even as they prated. Such are they whose works have perished in the world and the Hereafter. Such are they who are the losers.

(43) And never (O Muhammad) pray for one of them who dieth, nor stand by his grave. Lo! they disbelieved in Allah and His messenger, and they died while they were evil-doers.

(44) Let not their wealth nor their children please thee! Allah purposeth only to punish them thereby in the world, and that their souls shall pass away while they are disbelievers.

(45) But as for those in whose hearts is disease, it only addeth wickedness to their wickedness, and they die while they are disbelievers.

(46) Unto Him is the return of all of you; it is a promise of Allah in truth. Lo! He produceth creation, then reproduceth it, that He may reward those who believe and do good works with equity; while, as for those who disbelieve, theirs will be a boiling drink and painful doom because they disbelieved.

(47) And if misfortune touch a man he crieth unto Us, (while reclining) on his side, or sitting or standing, but when We have relieved him of the misfortune he goeth his way as though he had not cried unto Us because of a misfortune that afflicted him. Thus is what they do made (seeming) fair unto the prodigal.

(48) But they denied him, so We saved him and those with him in the ship, and made them viceroys (in the earth), while We drowned those who denied Our revelations. See then the nature of the consequence for those who had been warned.

(49) If only there had been a community (of all those that were destroyed of old) that believed and profited by its belief as did the folk of Jonah! When they believed We drew off from them the torment of disgrace in the life of the world and gave them comfort for a while.

(50) It was said (unto him): O Noah! Go thou down (from the mountain) with peace from Us and blessings upon thee and some nations (that will spring) from those with thee. (There will be other) nations unto whom We shall give enjoyment a long while and then a painful doom from Us will overtake them.
