The word(s) "therein" appears 248 time(s) in 225 verse(s) in Quran in Mohsin Khan translation.

(41) Allah will say: "This is a Day on which the truthful will profit from their truth: theirs are Gardens under which rivers flow (in Paradise) - they shall abide therein forever. Allah is pleased with them and they with Him. That is the great success (Paradise).

(42) To Allah belongs the dominion of the heavens and the earth and all that is therein, and He is Able to do all things.

(43) And of them there are some who listen to you; but We have set veils on their hearts, so they understand it not, and deafness in their ears; and even if they see every one of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) they will not believe therein; to the point that when they come to you to argue with you, the disbelievers say: "These are nothing but tales of the men of old."

(44) They are those whom We gave the Book, Al-Hukm (understanding of the religious laws), and Prophethood. But if these disbelieve therein (the Book, Al-Hukm and Prophethood), then, indeed We have entrusted it to a people (such as the Companions of Prophet Muhammad صلى الله عليه وسلم) who are not disbelievers therein.

(45) And they swear their strongest oaths by Allah, that if there came to them a sign, they would surely believe therein. Say: "Signs are but with Allah and what will make you (Muslims) perceive that (even) if it (the sign) came, they will not believe?"

(46) And We shall turn their hearts and their eyes away (from guidance), as they refused to believe therein for the first time, and We shall leave them in their trespass to wander blindly.

(47) And thus We have set up in every town great ones of its wicked people to plot therein. But they plot not except against their ownselves, and they perceive (it) not.

(48) And on the Day when He will gather them (all) together (and say): "O you assembly of jinn! Many did you mislead of men," and their Auliya' (friends and helpers) amongst men will say: "Our Lord! We benefited one from the other, but now we have reached our appointed term which You did appoint for us." He will say: "The Fire be your dwelling-place, you will dwell therein forever, except as Allah may will. Certainly your Lord is All-Wise, All-Knowing."

(49) And they say: "What is in the bellies of such and such cattle (milk or foetus) is for our males alone, and forbidden to our females (girls and women), but if it is born dead, then all have shares therein." He will punish them for their attribution (of such false orders to Allah). Verily, He is All-Wise, All-Knower. (Tafsir At-Tabari).

(50) And surely, We gave you authority on the earth and appointed for you therein provisions (for your life). Little thanks do you give.
