The word(s) "which" appears 700 time(s) in 620 verse(s) in Quran in Muhammad Habib Shakir translation.

(101) And We have revealed to you the Book with the truth, verifying what is before it of the Book and a guardian over it, therefore judge between them by what Allah has revealed, and do not follow their low desires (to turn away) from the truth that has come to you; for every one of you did We appoint a law and a way, and if Allah had pleased He would have made you (all) a single people, but that He might try you in what He gave you, therefore strive with one another to hasten to virtuous deeds; to Allah is your return, of all (of you), so He will let you know that in which you differed;

(102) And you will see many of them striving with one another to hasten in sin and exceeding the limits, and their eating of what is unlawfully acquired; certainly evil is that which they do.

(103) Why do not the learned men and the doctors of law prohibit them from their speaking of what is sinful and their eating of what is unlawfully acquired? Certainly evil is that which they work.

(104) And if they had kept up the Taurat and the Injeel and that which was revealed to them from their Lord, they would certainly have eaten from above them and from beneath their feet there is a party of them keeping to the moderate course, and (as for) most of them, evil is that which they do

(105) Say: O followers of the Book! you follow no good till you keep up the Taurat and the Injeel and that which is revealed to you from your Lord; and surely that which has been revealed to you from your Lord shall make many of them increase in inordinacy and unbelief; grieve not therefore for the unbelieving people.

(106) Say: Do you serve besides Allah that which does not control for you any harm, or any profit? And Allah-- He is the Hearing, the Knowing.

(107) They used not to forbid each other the hateful things (which) they did; certainly evil was that which they did.

(108) You will see many of them befriending those who disbelieve; certainly evil is that which their souls have sent before for them, that Allah became displeased with them and in chastisement shall they abide.

(109) Therefore Allah rewarded them on account of what they said, with gardens in which rivers flow to abide in them; and this is the reward of those who do good (to others).

(110) O you who believe! do not forbid (yourselves) the good things which Allah has made lawful for you and do not exceed the limits; surely Allah does not love those who exceed the limits.
