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

(71) Say: "In the Bounty of Allah, and in His Mercy (i.e. Islam and the Qur'an); - therein let them rejoice." That is better than what (the wealth) they amass.

(72) He it is Who has appointed for you the night that you may rest therein, and the day to make things visible (to you). Verily, in this are Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) for a people who listen (i.e. those who think deeply).

(73) Whosoever desires the life of the world and its glitter, to them We shall pay in full (the wages of) their deeds therein, and they will have no diminution therein.

(74) They are those for whom there is nothing in the Hereafter but Fire, and vain are the deeds they did therein. And of no effect is that which they used to do.

(75) Can they (Muslims) who rely on a clear proof (the Qur'an) from their Lord, and whom a witness [Jibril (Gabriel عليه السلام)] from Him recites (follows) it (can they be equal with the disbelievers); and before it, came the Book of Musa (Moses), a guidance and a mercy, they believe therein, but those of the sects (Jews, Christians and all the other non-Muslim nations) that reject it (the Qur'an), the Fire will be their promised meeting-place. So be not in doubt about it (i.e. those who denied Prophet Muhammad صلى الله عليه و سلم and also denied all that which he brought from Allah. Surely, they will enter Hell). Verily, it is the truth from your Lord, but most of the mankind believe not.

(76) Those who hinder (others) from the Path of Allah (Islamic Monotheism), and seek a crookedness therein, while they are disbelievers in the Hereafter.

(77) Verily, those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, and humble themselves (in repentance and obedience) before their Lord, they will be dwellers of Paradise to dwell therein forever.

(78) (So it was) till when Our Command came and the oven gushed forth (water like fountains from the earth). We said: "Embark therein, of each kind two (male and female), and your family - except him against whom the Word has already gone forth - and those who believe. And none believed with him, except a few."

(79) And he [Nuh (Noah) عليه السلام] said: "Embark therein: in the Name of Allah will be its (moving) course and its (resting) anchorage. Surely, my Lord is Oft-Forgiving, Most Merciful." (Tafsir At-Tabari)

(80) And to Thamud (people We sent) their brother Salih. He said: "O my people! Worship Allah: you have no other ilah (god) but Him. He brought you forth from the earth and settled you therein, then ask forgiveness of Him and turn to Him in repentance. Certainly, my Lord is Near (to all by His Knowledge), Responsive."
