The word(s) "when" appears 708 time(s) in 647 verse(s) in Quran in Abdullah Yusuf Ali translation.

(321) Say, "I do but warn you according to revelation": But the deaf will not hear the call, (even) when they are warned!

(322) (Remember) Noah, when he cried (to Us) aforetime: We listened to his (prayer) and delivered him and his family from great distress.

(323) And remember David and Solomon, when they gave judgment in the matter of the field into which the sheep of certain people had strayed by night: We did witness their judgment.

(324) And (remember) Job, when He cried to his Lord, "Truly distress has seized me, but Thou art the Most Merciful of those that are merciful."

(325) And remember Zun-nun, when he departed in wrath: He imagined that We had no power over him! But he cried through the deptHs of darkness, "There is no god but thou: glory to thee: I was indeed wrong!"

(326) And (remember) Zakariya, when he cried to his Lord: "O my Lord! leave me not without offspring, though thou art the best of inheritors."

(327) O mankind! if ye have a doubt about the Resurrection, (consider) that We created you out of dust, then out of sperm, then out of a leech-like clot, then out of a morsel of flesh, partly formed and partly unformed, in order that We may manifest (our power) to you; and We cause whom We will to rest in the wombs for an appointed term, then do We bring you out as babes, then (foster you) that ye may reach your age of full strength; and some of you are called to die, and some are sent back to the feeblest old age, so that they know nothing after having known (much), and (further), thou seest the earth barren and lifeless, but when We pour down rain on it, it is stirred (to life), it swells, and it puts forth every kind of beautiful growth (in pairs).

(328) To those whose hearts when Allah is mentioned, are filled with fear, who show patient perseverance over their afflictions, keep up regular prayer, and spend (in charity) out of what We have bestowed upon them.

(329) The sacrificial camels we have made for you as among the symbols from Allah: in them is (much) good for you: then pronounce the name of Allah over them as they line up (for sacrifice): when they are down on their sides (after slaughter), eat ye thereof, and feed such as (beg not but) live in contentment, and such as beg with due humility: thus have We made animals subject to you, that ye may be grateful.

(330) Never did We send a messenger or a prophet before thee, but, when he framed a desire, Satan threw some (vanity) into his desire: but Allah will cancel anything (vain) that Satan throws in, and Allah will confirm (and establish) His Signs: for Allah is full of Knowledge and Wisdom:
