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

(471) Then which of the favours of your Lord will ye deny?-

(472) Then which of the favours of your Lord will ye deny?

(473) See ye the water which ye drink?

(474) See ye the Fire which ye kindle?

(475) Is it ye who grow the tree which feeds the fire, or do We grow it?

(476) which none shall touch but those who are clean:

(477) One Day shalt thou see the believing men and the believing women- how their Light runs forward before them and by their right hands: (their greeting will be): "Good News for you this Day! Gardens beneath which flow rivers! to dwell therein for aye! This is indeed the highest Achievement!"

(478) Has not the Time arrived for the Believers that their hearts in all humility should engage in the remembrance of Allah and of the Truth which has been revealed (to them), and that they should not become like those to whom was given Revelation aforetime, but long ages passed over them and their hearts grew hard? For many among them are rebellious transgressors.

(479) Know ye (all), that the life of this world is but play and amusement, pomp and mutual boasting and multiplying, (in rivalry) among yourselves, riches and children. Here is a similitude: How rain and the growth which it brings forth, delight (the hearts of) the tillers; soon it withers; thou wilt see it grow yellow; then it becomes dry and crumbles away. But in the Hereafter is a Penalty severe (for the devotees of wrong). And Forgiveness from Allah and (His) Good Pleasure (for the devotees of Allah). And what is the life of this world, but goods and chattels of deception?

(480) Be ye foremost (in seeking) Forgiveness from your Lord, and a Garden (of Bliss), the width whereof is as the width of heaven and earth, prepared for those who believe in Allah and His messengers: that is the Grace of Allah, which He bestows on whom he pleases: and Allah is the Lord of Grace abounding.
