The word(s) "therein" appears 220 time(s) in 195 verse(s) in Quran in Muhammad Pickthal translation.

(41) And thus have We made in every city great ones of its wicked ones, that they should plot therein. They do but plot against themselves, though they perceive not.

(42) In the day when He will gather them together (He will say): O ye assembly of the jinn! Many of humankind did ye seduce. And their adherents among humankind will say: Our Lord! We enjoyed one another, but now we have arrived at the appointed term which Thou appointedst for us. He will say: Fire is your home. Abide therein for ever, save him whom Allah willeth (to deliver). Lo! thy Lord is Wise, Aware.

(43) And We have given you (mankind) power in the earth, and appointed for you therein livelihoods. Little give ye thanks!

(44) But they who deny Our revelations and scorn them - each are rightful owners of the Fire; they will abide therein.

(45) But (as for) those who believe and do good works - We tax not any soul beyond its scope - Such are rightful owners of the Garden. They abide therein.

(46) And We wrote for him, upon the tablets, the lesson to be drawn from all things and the explanation of all things, then (bade him): Hold it fast; and command thy people (saying): Take the better (course made clear) therein. I shall show thee the abode of evil-livers.

(47) And a generation hath succeeded them who inherited the scriptures. They grasp the goods of this low life (as the price of evil-doing) and say: It will be forgiven us. And if there came to them (again) the offer of the like, they would accept it (and would sin again). Hath not the covenant of the Scripture been taken on their behalf that they should not speak aught concerning Allah save the truth? And they have studied that which is therein. And the abode of the Hereafter is better, for those who ward off (evil). Have ye then no sense?

(48) And when We shook the Mount above them as it were a covering, and they supposed that it was going to fall upon them (and We said): Hold fast that which We have given you, and remember that which is therein, that ye may ward off (evil).

(49) Know they not that whoso opposeth Allah and His messenger, his verily is fire of hell, to abide therein? That is the extreme abasement.

(50) Never stand (to pray) there. A place of worship which was found upon duty (to Allah) from the first day is more worthy that thou shouldst stand (to pray) therein, wherein are men who love to purify themselves. Allah loveth the purifiers.
