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

(11) And those who believe (in the Oneness of Allah تعالى - Islamic Monotheism) and do righteous good deeds, they are dwellers of Paradise, they will dwell therein forever. (See V. 2:257)

(12) Those (who embraced Islam from Bani Israel) to whom We gave the Book [the Taurat (Torah)] [or those (Muhammad's صلى الله عليه وسلم companions) to whom We have given the Book (the Qur'an)] recite it (i.e. obey its orders and follow its teachings) as it should be recited (i.e. followed), they are the ones who believe therein. And whoso disbelieve in it (the Qur'an), those are they who are the losers. (Tafsir Al-Qurtubi).

(13) They will abide therein (under the curse in Hell), their punishment will neither be lightened, nor will they be reprieved.

(14) Verily! In the creation of the heavens and the earth, and in the alternation of night and day, and the ships which sail through the sea with that which is of use to mankind, and the water (rain) which Allah sends down from the sky and makes the earth alive therewith after its death, and the moving (living) creatures of all kinds that He has scattered therein, and in the veering of winds and clouds which are held between the sky and the earth, are indeed Ayat (proofs, evidence, signs, etc.) for people of understanding.

(15) The Hajj (pilgrimage) is (in) the well-known (lunar year) months (i.e. the 10th month, the 11th month and the first ten days of the 12th month of the Islamic calendar, i.e. two months and ten days). So whosoever intends to perform Hajj therein (by assuming Ihram), then he should not have sexual relations (with his wife), nor commit sin, nor dispute unjustly during the Hajj. And whatever good you do, (be sure) Allah knows it. And take a provision (with you) for the journey, but the best provision is At-Taqwa (piety, righteousness). So fear Me, O men of understanding!

(16) And when he turns away (from you "O Muhammad "صلى الله عليه وسلم"), his effort in the land is to make mischief therein and to destroy the crops and the cattle, and Allah likes not mischief.

(17) They ask you concerning fighting in the Sacred Months (i.e. 1st, 7th, 11th and 12th months of the Islamic calendar). Say "Fighting therein is a great (transgression) but a greater (transgression) with Allah is to prevent mankind from following the Way of Allah, to disbelieve in Him, to prevent access to Al-Masjid-Al-Haram (at Makkah), and to drive out its inhabitants, and Al-Fitnah is worse than killing. And they will never cease fighting you until they turn you back from your religion (Islamic Monotheism) if they can. And whosoever of you turns back from his religion and dies as a disbeliever, then his deeds will be lost in this life and in the Hereafter, and they will be the dwellers of the Fire. They will abide therein forever."

(18) Allah is the Wali (Protector or Guardian) of those who believe. He brings them out from darkness into light. But as for those who disbelieve, their Auliya (supporters and helpers) are Taghut [false deities and false leaders], they bring them out from light into darkness. Those are the dwellers of the Fire, and they will abide therein forever. (See V.2:81,82)

(19) Would any of you wish to have a garden with date-palms and vines, with rivers flowing underneath, and all kinds of fruits for him therein, while he is striken with old age, and his children are weak (not able to look after themselves), then it is struck with a fiery whirlwind, so that it is burnt? Thus does Allah make clear His Ayat (proofs, evidence, verses) to you that you may give thought.

(20) O you who believe! Spend of the good things which you have (legally) earned, and of that which We have produced from the earth for you, and do not aim at that which is bad to spend from it, (though) you would not accept it save if you close your eyes and tolerate therein. And know that Allah is Rich (Free of all needs), and Worthy of all praise.
