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

(191) Say: "Will you inform Allah of your religion while Allah knows all that is in the heavens and all that is in the earth, and Allah is All-Aware of everything.

(192) Verily, therein is indeed a reminder for him who has a heart or gives ear while he is heedful.

(193) And in Thamud (there is also a sign), when they were told: "Enjoy yourselves for a while!"

(194) But they insolently defied the Command of their Lord, so the Sa'iqah overtook them while they were looking.

(195) while he [Jibril (Gabriel)] was in the highest part of the horizon, (Tafsir Ibn Kathir)

(196) And what is the matter with you that you believe not in Allah! while the Messenger (Muhammad صلى الله عليه وسلم) invites you to believe in your Lord (Allah); and He (Allah) has indeed taken your covenant, if you are real believers.

(197) On the Day when Allah will resurrect them all together (i.e. on the Day of Resurrection) and inform them of what they did. Allah has kept account of it, while they have forgotten it. And Allah is Witness over all things.

(198) Have you not seen that Allah knows whatsoever is in the heavens and whatsoever is on the earth? There is no Najwa (secret counsel) of three but He is their fourth (with His Knowledge, while He Himself is over the Throne, over the seventh heaven), nor of five but He is their sixth (with His Knowledge), nor of less than that or more but He is with them (with His Knowledge) wheresoever they may be. And afterwards on the Day of Resurrection He will inform them of what they did. Verily, Allah is the All-Knower of everything.

(199) Have you (O Muhammad صلى الله عليه وسلم) not seen those (hypocrites) who take as friends a people upon whom is the Wrath of Allah (i.e. Jews)? They are neither of you (Muslims) nor of them (Jews), and they swear to a lie while they know.

(200) O you who believe! Take not My enemies and your enemies (i.e. disbelievers and polytheists) as friends, showing affection towards them, while they have disbelieved in what has come to you of the truth (i.e. Islamic Monotheism, this Qur'an, and Muhammad صلى الله عليه وسلم), and have driven out the Messenger (Muhammad صلى الله عليه وسلم) and yourselves (from your homeland) because you believe in Allah your Lord! If you have come forth to strive in My Cause and to seek My Good Pleasure, (then take not these disbelievers and polytheists as your friends). You show friendship to them in secret, while I am All-Aware of what you conceal and what you reveal. And whosoever of you (Muslims) does that, then indeed he has gone (far) astray from the Straight Path .
