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

(11) And when We said unto the angels: Prostrate yourselves before Adam, they fell prostrate, all save Iblis. He demurred through pride, and so became a disbeliever.

(12) And guard yourselves against a day when no soul will in aught avail another, nor will intercession be accepted from it, nor will compensation be received from it, nor will they be helped.

(13) And (remember) when We did deliver you from Pharaoh's folk, who were afflicting you with dreadful torment, slaying your sons and sparing your women: that was a tremendous trial from your Lord.

(14) And when We brought you through the sea and rescued you, and drowned the folk of Pharaoh in your sight.

(15) And when We did appoint for Moses forty nights (of solitude), and then ye chose the calf, when he had gone from you, and were wrong-doers.

(16) And when We gave unto Moses the Scripture and the criterion (of right and wrong), that ye might be led aright.

(17) And when Moses said unto his people: O my people! Ye have wronged yourselves by your choosing of the calf (for worship) so turn in penitence to your Creator, and kill (the guilty) yourselves. That will be best for you with your Creator and He will relent toward you. Lo! He is the Relenting, the Merciful.

(18) And when ye said: O Moses! We will not believe in thee till we see Allah plainly; and even while ye gazed the lightning seized you.

(19) And when We said: Go into this township and eat freely of that which is therein, and enter the gate prostrate, and say: "Repentance." We will forgive you your sins and will increase (reward) for the right-doers.

(20) And when Moses asked for water for his people, We said: Smite with thy staff the rock. And there gushed out therefrom twelve springs (so that) each tribe knew their drinking-place. Eat and drink of that which Allah hath provided, and do not act corruptly, making mischief in the earth.
