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

(571) And it behoves not a believing man and a believing woman that they should have any choice in their matter when Allah and His Apostle have decided a matter; and whoever disobeys Allah and His Apostle, he surely strays off a manifest straying.

(572) And when you said to him to whom Allah had shown favor and to whom you had shown a favor: Keep your wife to yourself and be careful of (your duty to) Allah; and you concealed in your soul what Allah would bring to light, and you feared men, and Allah had a greater right that you should fear Him. But when Zaid had accomplished his want of her, We gave her to you as a wife, so that there should be no difficulty for the believers in respect of the wives of their adopted sons, when they have accomplished their want of them; and Allah's command shall be performed.

(573) O you who believe! when you marry the believing women, then divorce them before you touch them, you have in their case no term which you should reckon; so make some provision for them and send them forth a goodly sending forth.

(574) O you who believe! do not enter the houses of the Prophet unless permission is given to you for a meal, not waiting for its cooking being finished-- but when you are invited, enter, and when you have taken the food, then disperse-- not seeking to listen to talk; surely this gives the Prophet trouble, but he forbears from you, and Allah does not forbear from the truth And when you ask of them any goods, ask of them from behind a curtain; this is purer for your hearts and (for) their hearts; and it does not behove you that you should give trouble to the Apostle of Allah, nor that you should marry his wives after him ever; surely this is grievous in the sight of Allah.

(575) On the day when their faces shall be turned back into the fire, they shall say: O would that we had obeyed Allah and obeyed the Apostle!

(576) And those who disbelieve say: Shall we point out to you a man who informs you that when you are scattered the utmost scattering you shall then be most surely (raised) in (to) a new creation?

(577) But when We decreed death for him, naught showed them his death but a creature of the earth that ate away his staff; and when it fell down, the jinn came to know plainly that if they had known the unseen, they would not have tarried in abasing torment.

(578) And intercession will not avail aught with Him save of him whom He permits. Until when fear shall be removed from their hearts, They shall say: What is it that your Lord said? They shall say: The truth. And He is the Most High, the Great.

(579) And they say: when will this promise be (fulfilled) if you are truthful?

(580) And those who disbelieve say: By no means will we believe in this Quran, nor in that which is before it; and could you see when the unjust shall be made to stand before their Lord, bandying words one with another! Those who were reckoned weak shall say to those who were proud: Had it not been for you we would certainly have been believers.
