The word(s) "which" appears 609 time(s) in 551 verse(s) in Quran in Abdullah Yusuf Ali translation.

(411) Such are they from whom We shall accept the best of their deeds and pass by their ill deeds: (They shall be) among the Companions of the Garden: a promise! of truth, which was made to them (in this life).

(412) And to all are (assigned) degrees according to the deeds which they (have done), and in order that (Allah) may recompense their deeds, and no injustice be done to them.

(413) They said: "Hast thou come in order to turn us aside from our gods? Then bring upon us the (calamity) with which thou dost threaten us, if thou art telling the truth?"

(414) He said: "The Knowledge (of when it will come) is only with Allah: I proclaim to you the mission on which I have been sent: But I see that ye are a people in ignorance!"..

(415) And We had firmly established them in a (prosperity and) power which We have not given to you (ye Quraish!) and We had endowed them with (faculties of) hearing, seeing, heart and intellect: but of no profit to them were their (faculties of) hearing, sight, and heart and intellect, when they went on rejecting the Signs of Allah; and they were (completely) encircled by that which they used to mock at!

(416) And admit them to the Garden which He has announced for them.

(417) Verily Allah will admit those who believe and do righteous deeds, to Gardens beneath which rivers flow; while those who reject Allah will enjoy (this world) and eat as cattle eat; and the Fire will be their abode.

(418) And how many cities, with more power than thy city which has driven thee out, have We destroyed (for their sins)? and there was none to aid them.

(419) (Here is) a Parable of the Garden which the righteous are promised: in it are rivers of water incorruptible; rivers of milk of which the taste never changes; rivers of wine, a joy to those who drink; and rivers of honey pure and clear. In it there are for them all kinds of fruits; and Grace from their Lord. (Can those in such Bliss) be compared to such as shall dwell for ever in the Fire, and be given, to drink, boiling water, so that it cuts up their bowels (to pieces)?

(420) This because they followed that which called forth the Wrath of Allah, and they hated Allah's good pleasure; so He made their deeds of no effect.
