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

(261) He it is Who makes you travel by land and sea; until when you are in the ships, and they sail on with them in a pleasant breeze, and they rejoice, a violent wind overtakes them and the billows surge in on them from all sides, and they become certain that they are encompassed about, they pray to Allah, being sincere to Him in obedience: If Thou dost deliver us from this, we will most certainly be of the grateful ones.

(262) But when He delivers them, lo! they are unjustly rebellious in the earth. O men! your rebellion is against your own souls-- provision (only) of this world's life-- then to Us shall be your return, so We will inform you of what you did.

(263) The likeness of this world's life is only as water which We send down from the cloud, then the herbage of the earth of which men and cattle eat grows luxuriantly thereby, until when the earth puts on its golden raiment and it becomes garnished, and its people think that they have power over it, Our command comes to it, by night or by day, so We render it as reaped seed; produce, as though it had not been in existence yesterday; thus do We make clear the communications for a people who reflect.

(264) And on the day when We will gather them all together, then We will say to those who associated others (with Allah): Keep where you are, you and your associates; then We shall separate them widely one from another and their associates would say: It was not us that you served:

(265) And on the day when He will gather them as though they had not stayed but an hour of the day, they will know each other. They will perish indeed who called the meeting with Allah to be a lie, and they are not followers of the right direction.

(266) And every nation had an apostle; so when their apostle came, the matter was decided between them with justice and they shall not be dealt with unjustly.

(267) And they say: when will this threat come about, if you are truthful?

(268) Say: I do not control for myself any harm, or any benefit except what Allah pleases; every nation has a term; when their term comes, they shall not then remain behind for an hour, nor can they go before (their time).

(269) And when it comes to pass, will you believe in it? What! now (you believe), and already you wished to have it hastened on.

(270) And if every soul that has done injustice had all that is in the earth, it would offer it for ransom, and they will manifest regret when they see the chastisement and the matter shall be decided between them with justice and they shall not be dealt with unjustly.
