The word(s) "when" appears 926 time(s) in 834 verse(s) in Quran in Muhammad Habib Shakir translation.

(621) Those before them rejected (prophets), therefore there came to them the chastisement from whence they perceived not.

(622) Who is then more unjust than he who utters a lie against Allah and (he who) gives the lie to the truth when it comes to him; is there not in hell an abode for the unbelievers?

(623) And when Allah alone is mentioned, the hearts of those who do not believe in the hereafter shrink, and when those besides Him are mentioned, lo! they are joyful.

(624) So when harm afflicts a man he calls upon Us; then, when We give him a favor from Us, he says: I have been given it only by means of knowledge. Nay, it is a trial, but most of them do not know.

(625) Or it should say when it sees the punishment: Were there only a returning for me, I should be of the doers of good.

(626) And those who disbelieve shall be driven to hell in companies; until, when they come to it, its doors shall be opened, and the keepers of it shall say to them: Did not there come to you apostles from among you reciting to you the communications of your Lord and warning you of the meeting of this day of yours? They shall say: Yea! But the sentence of punishment was due against the unbelievers.

(627) And those who are careful of (their duty to) their Lord shall be conveyed to the garden in companies; until when they come to it, and its doors shall be opened, and the keepers of it shall say to them: Peace be on you, you shall be happy; therefore enter it to abide.

(628) Surely those who disbelieve shall be cried out to: Certainly Allah's hatred (of you) when you were called upon to the faith and you rejected, is much greater than your hatred of yourselves.

(629) That is because when Allah alone was called upon, you disbelieved, and when associates were given to Him, you believed; so judgment belongs to Allah, the High, the Great.

(630) (Of) the day when they shall come forth, nothing concerning them remains hidden to Allah. To whom belongs the kingdom this day? To Allah, the One, the Subduer (of all).
