The word(s) "which" appears 877 time(s) in 758 verse(s) in Quran in Mohsin Khan translation.

(721) So leave them to plunge in vain talk and play about, until they meet their Day which they are promised -

(722) With their eyes lowered in fear and humility, ignominy covering them (all over)! That is the Day which they were promised!

(723) 'And that the foolish among us [i.e. Iblis (Satan) or the polytheists amongst the jinn] used to utter against Allah that which was an enormity in falsehood.

(724) Till, when they see that which they are promised, then they will know who it is that is weaker concerning helpers and less important concerning numbers.

(725) Say (O Muhammad صلى الله عليه وسلم): "I know not whether (the punishment) which you are promised is near or whether my Lord will appoint for it a distant term.

(726) [He (Allah) protects them (the Messengers)], till He sees that they (the Messengers) have conveyed the Messages of their Lord (Allah). And He (Allah) surrounds all that which is with them, and He (Allah) keeps count of all things (i.e. He knows the exact number of everything).

(727) And We have set none but angels as guardians of the Fire. And We have fixed their number (19) only as a trial for the disbelievers, in order that the people of the Scripture (Jews and Christians) may arrive at a certainty [that this Qur'an is the truth as it agrees with their Books regarding the number (19) which is written in the Taurat (Torah) and the Injeel (Gospel)] and that the believers may increase in Faith (as this Qur'an is the truth), and that no doubt may be left for the people of the Scripture and the believers, and that those in whose hearts is a disease (of hypocrisy) and the disbelievers may say: "What Allah intends by this (curious) example ?" Thus Allah leads astray whom He wills and guides whom He wills. And none can know the hosts of your Lord but He. And this (Hell) is nothing else than a (warning) reminder to mankind.

(728) "And we used to talk falsehood (all that which Allah hated) with vain talkers.

(729) (It will be said to the disbelievers): "Depart you to that which you used to deny!

(730) "Eat and drink comfortably for that which you used to do."
