The word(s) "when" appears 1006 time(s) in 918 verse(s) in Quran in Muhammad Pickthal translation.

(721) And when the son of Mary is quoted as an example, behold! the folk laugh out,

(722) when Jesus came with clear proofs (of Allah's Sovereignty), he said: I have come unto you with wisdom, and to make plain some of that concerning which ye differ. So keep your duty to Allah, and obey me.

(723) Await they aught save the Hour, that it shall come upon them suddenly, when they know not?

(724) Therein for you is fruit in plenty whence to eat.

(725) But watch thou (O Muhammad) for the day when the sky will produce visible smoke

(726) How can there be remembrance for them, when a messenger making plain (the Truth) had already come unto them,

(727) On the day when We shall seize them with the greater seizure, (then) in truth We shall punish.

(728) And verily We tried before them Pharaoh's folk, when there came unto them a noble messenger,

(729) A day when friend can in naught avail friend, nor can they be helped,

(730) And when he knoweth aught of Our revelations he maketh it a jest. For such there is a shameful doom.
