The word(s) "wherein" appears 90 time(s) in 90 verse(s) in Quran in Muhammad Pickthal translation.

(51) Then We produce for you therewith gardens of date-palms and grapes, wherein is much fruit for you and whereof ye eat;

(52) (Here is) a surah which We have revealed and enjoined, and wherein We have revealed plain tokens, that haply ye may take heed.

(53) (It is) no sin for you to enter uninhabited houses wherein is comfort for you. Allah knoweth what ye proclaim and what ye hide.

(54) Allah is the Light of the heavens and the earth. The similitude of His light is as a niche wherein is a lamp. The lamp is in a glass. The glass is as it were a shining star. (This lamp is) kindled from a blessed tree, an olive neither of the East nor of the West, whose oil would almost glow forth (of itself) though no fire touched it. Light upon light. Allah guideth unto His light whom He will. And Allah speaketh to mankind in allegories, for Allah is Knower of all things.

(55) Hast thou not seen how Allah wafteth the clouds, then gathereth them, then maketh them layers, and thou seest the rain come forth from between them; He sendeth down from the heaven mountains wherein is hail, and smiteth therewith whom He will, and averteth it from whom He will. The flashing of His lightning all but snatcheth away the sight.

(56) Say: Have ye thought, if Allah made day everlasting for you till the Day of Resurrection, who is a god beside Allah who could bring you night wherein ye rest? Will ye not then see?

(57) wherein they will abide. It is a promise of Allah in truth. He is the Mighty, the Wise.

(58) And if it be said unto them: Follow that which Allah hath revealed, they say: Nay, but we follow that wherein we found our fathers. What! Even though the devil were inviting them unto the doom of flame?

(59) Lo! thy Lord will judge between them on the Day of Resurrection concerning that wherein they used to differ.

(60) wherein they will abide for ever. They will find (then) no protecting friend nor helper.
