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

(641) Coin for them a similitude: The people of the city when those sent (from Allah) came unto them;

(642) when We sent unto them twain, and they denied them both, so We reinforced them with a third, and they said: Lo! we have been sent unto you.

(643) Shall I take (other) gods in place of Him when, if the Beneficent should wish me any harm, their intercession will avail me naught, nor can they save?

(644) when it is said unto them: Beware of that which is before you and that which is behind you, that haply ye may find mercy (they are heedless).

(645) And when it is said unto them: Spend of that wherewith Allah hath provided you, those who disbelieve say unto those who believe: Shall we feed those whom Allah, if He willed, would feed? Ye are in naught else than error manifest.

(646) And they say: when will this promise be fulfilled, if ye are truthful?

(647) And he hath coined for Us a similitude, and hath forgotten the fact of his creation, saying: Who will revive these bones when they have rotted away?

(648) But His command, when He intendeth a thing, is only that He saith unto it: Be! and it is.

(649) Nay, but thou dost marvel when they mock

(650) And heed not when they are reminded,
