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

(321) For his sake there are angels following one another, before him and behind him, who guard him by Allah's commandment; surely Allah does not change the condition of a people until they change their own condition; and when Allah intends evil to a people, there is no averting it, and besides Him they have no protector.

(322) And when Musa said to his people: Call to mind Allah's favor to you when He delivered you from Firon's people, who subjected you to severe torment, and slew your sons and spared your women; and in this there was a great trial from your Lord.

(323) And when your Lord made it known: If you are grateful, I would certainly give to you more, and if you are ungrateful, My chastisement is truly severe.

(324) And when Ibrahim said: My Lord! make this city secure, and save me and my sons from worshipping idols:

(325) O our Lord! grant me protection and my parents and the believers on the day when the reckoning shall come to pass!

(326) And warn people of the day when the chastisement shall come to them, then those who were unjust will say: O our Lord! respite us to a near term, (so) we shall respond to Thy call and follow the apostles. What! did you not swear before (that) there will be no passing away for you!

(327) On the day when the earth shall be changed into a different earth, and the heavens (as well), and they shall come forth before Allah, the One, the Supreme.

(328) And when your Lord said to the angels: Surely I am going to create a mortal of the essence of black mud fashioned in shape.

(329) So when I have made him complete and breathed into him of My spirit, fall down making obeisance to him.

(330) He said: My Lord! then respite me till the time when they are raised.
