The word(s) "when" appears 926 time(s) in 834 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) And when We delivered you from Firon's people, who subjected you to severe torment, killing your sons and sparing your women, and in this there was a great trial from your Lord.

(12) And when We parted the sea for you, so We saved you and drowned the followers of Firon and you watched by.

(13) And when We appointed a time of forty nights with Musa, then you took the calf (for a god) after him and you were unjust.

(14) And when We gave Musa the Book and the distinction that you might walk aright.

(15) And when Musa said to his people: O my people! you have surely been unjust to yourselves by taking the calf (for a god), therefore turn to your Creator (penitently), so kill your people, that is best for you with your Creator: so He turned to you (mercifully), for surely He is the Oft-returning (to mercy), the Merciful.

(16) And when you said: O Musa! we will not believe in you until we see Allah manifestly, so the punishment overtook you while you looked on.

(17) And when We said: Enter this city, then eat from it a plenteous (food) wherever you wish, and enter the gate making obeisance, and say, forgiveness. We will forgive you your wrongs and give more to those who do good (to others).

(18) And when Musa prayed for drink for his people, We said: Strike the rock with your staff. So there gushed from it twelve springs; each tribe knew its drinking place: Eat and drink of the provisions of Allah and do not act corruptly in the land, making mischief.

(19) And when you said: O Musa! we cannot bear with one food, therefore pray Lord on our behalf to bring forth for us out of what the earth grows, of its herbs and its cucumbers and its garlic and its lentils and its onions. He said: Will you exchange that which is better for that which is worse? Enter a city, so you will have what you ask for. And abasement and humiliation were brought down upon them, and they became deserving of Allah's wrath; this was so because they disbelieved in the communications of Allah and killed the prophets unjustly; this was so because they disobeyed and exceeded the limits.

(20) And when We took a promise from you and lifted the mountain over you: Take hold of the law (Tavrat) We have given you with firmness and bear in mind what is in it, so that you may guard (against evil).
