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

(201) So the end of both will be that they will be in the Fire, abiding therein. Such is the recompense of the Zalimun (i.e. polytheists, wrong-doers, disbelievers in Allah and in His Oneness).

(202) (And remember) the Day when He will gather you (all) on the Day of Gathering, - that will be the Day of mutual loss and gain (i.e. loss for the disbelievers as they will enter the Hell-fire and gain for the believers as they will enter Paradise). And whosoever believes in Allah and performs righteous good deeds, He will expiate from him his sins, and will admit him to Gardens under which rivers flow (Paradise) to dwell therein forever; that will be the great success.

(203) But those who disbelieved (in the Oneness of Allah - Islamic Monotheism) and denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they will be the dwellers of the Fire, to dwell therein forever. And worst indeed is that destination .

(204) (And has also sent to you) a Messenger (Muhammad صلى الله عليه وسلم), who recites to you the Verses of Allah (the Qur'an) containing clear explanations, that He may take out those who believe and do righteous good deeds, from the darkness (of polytheism and disbelief) to the light (of Islamic Monotheism). And whosoever believes in Allah and performs righteous good deeds, He will admit him into Gardens under which rivers flow (Paradise) to dwell therein forever. Allah has indeed granted for him an excellent provision.

(205) When they are cast therein, they will hear the (terrible) drawing in of its breath as it blazes forth.

(206) It almost bursts up with fury. Every time a group is cast therein, its keeper will ask: "Did no warner come to you?"

(207) That you shall therein have all that you choose?

(208) And has made the moon a light therein, and made the sun a lamp?

(209) That you may go about therein in broad roads.

(210) 'It guides to the Right Path, and we have believed therein, and we shall never join (in worship) anything with our Lord (Allah).
