The word(s) "herein" appears 288 time(s) in 262 verse(s) in Quran in Mohsin Khan translation.

(101) "(It will be said to them): 'Enter therein (Paradise), in peace and security.'

(102) Surely! Therein is indeed a sign for the believers.

(103) And wherein is beauty for you, when you bring them home in the evening, and as you lead them forth to pasture in the morning.

(104) "So enter the gates of Hell, to abide therein, and indeed, what an evil abode will be for the arrogant."

(105) 'Adn (Eden) Paradise (Gardens of Eternity) which they will enter, under which rivers flow, they will have therein all that they wish. Thus Allah rewards the Muttaqun (the pious - See V.2:2).

(106) In order that He may make manifest to them the truth of that wherein they differ, and that those who disbelieved (in Resurrection, and in the Oneness of Allah) may know that they were liars.

(107) And from the fruits of date-palms and grapes, you derive strong drink and a goodly provision. Verily, therein is indeed a sign for people who have wisdom.

(108) "Then, eat of all fruits, and follow the ways of your Lord made easy (for you)." There comes forth from their bellies, a drink of varying colour wherein is healing for men. Verily, in this is indeed a sign for people who think.

(109) And be not like her who undoes the thread which she has spun, after it has become strong, by taking your oaths as a means of deception among yourselves, lest a nation should be more numerous than another nation. Allah only tests you by this [i.e who obeys Allah and fulfils Allah's Covenant and who disobeys Allah and breaks Allah's Covenant]. And on the Day of Resurrection, He will certainly make clear to you that wherein you used to differ [i.e. a believer confesses and believes in the Oneness of Allah and in the Prophethood of Prophet Muhammad صلى الله عليه و سلم which the disbeliever denies and that is their difference amongst them in the life of this world] .

(110) The Sabbath was only prescribed for those who differed concerning it, and verily, your Lord will judge between them on the Day of Resurrection about that wherein they used to differ.
