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

(611) But when it shall descend in their court, evil shall then be the morning of the warned ones.

(612) And has there come to you the story of the litigants, when they made an entry into the private chamber by ascending over the walls?

(613) when they entered in upon Dawood and he was frightened at them, they said: Fear not; two litigants, of whom one has acted wrongfully towards the other, therefore decide between us with justice, and do not act unjustly, and guide us to the right way.

(614) when there were brought to him in the evening (horses) still when standing, swift when running--

(615) And remember Our servant Ayyub, when he called upon his Lord: The Shaitan has afflicted me with toil and torment.

(616) I had no knowledge of the exalted chiefs when they contended:

(617) when your Lord said to the angels; Surely I am going to create a mortal from dust:

(618) So when I have made him complete and breathed into him of My spirit, then fall down making obeisance to him.

(619) He has created you from a single being, then made its mate of the same (kind), and He has made for you eight of the cattle in pairs. He creates you in the wombs of your mothers-- a creation after a creation-- in triple darkness; that is Allah your Lord, His is the kingdom; there is no god but He; whence are you then turned away?

(620) And when distress afflicts a man he calls upon his Lord turning to Him frequently; then when He makes him possess a favor from Him, he forgets that for which he called upon Him before, and sets up rivals to Allah that he may cause (men) to stray off from His path. Say: Enjoy yourself in your ungratefulness a little, surely you are of the inmates of the fire.
