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

(221) And Moses chose of his people seventy men for Our appointed tryst and, when the trembling came on them, he said: My Lord! If Thou hadst willed Thou hadst destroyed them long before, and me with them. Wilt thou destroy us for that which the ignorant among us did? It is but Thy trial (of us). Thou sendest whom Thou wilt astray and guidest whom Thou wilt: Thou art our Protecting Friend, therefore forgive us and have mercy on us, Thou, the Best of all who show forgiveness.

(222) We divided them into twelve tribes, nations; and We inspired Moses, when his people asked him for water, saying: Smite with thy staff the rock! And there gushed forth therefrom twelve springs, so that each tribe knew their drinking-place. And we caused the white cloud to overshadow them and sent down for them the manna and the quails (saying): Eat of the good things wherewith we have provided you. They wronged Us not, but they were wont to wrong themselves.

(223) And when it was said unto them: Dwell in this township and eat therefrom whence ye will, and say "Repentance," and enter the gate prostrate; We shall forgive you your sins; We shall increase (reward) for the right-doers.

(224) Ask them (O Muhammad) of the township that was by the sea, how they did break the Sabbath, how their big fish came unto them visibly upon their Sabbath day and on a day when they did not keep Sabbath came they not unto them. Thus did We try them for that they were evil-livers.

(225) And when a community among them said: Why preach ye to a folk whom Allah is about to destroy or punish with an awful doom, they said: In order to be free from guilt before your Lord, and that haply they may ward off (evil).

(226) And when they forgot that whereof they had been reminded, We rescued those who forbade wrong, and visited those who did wrong with dreadful punishment because they were evil-livers.

(227) So when they took pride in that which they had been forbidden, We said unto them: Be ye apes despised and loathed!

(228) And (remember) when thy Lord proclaimed that He would raise against them till the Day of Resurrection those who would lay on them a cruel torment. Lo! verily thy Lord is swift in prosecution and lo! verily He is Forgiving, Merciful.

(229) And when We shook the Mount above them as it were a covering, and they supposed that it was going to fall upon them (and We said): Hold fast that which We have given you, and remember that which is therein, that ye may ward off (evil).

(230) And (remember) when thy Lord brought forth from the Children of Adam, from their reins, their seed, and made them testify of themselves, (saying): Am I not your Lord? They said: Yea, verily. We testify. (That was) lest ye should say at the Day of Resurrection: Lo! of this we were unaware;
