The word(s) "when" appears 916 time(s) in 828 verse(s) in Quran in Mohsin Khan translation.

(111) when there comes to them some matter touching (public) safety or fear, they make it known (among the people); if only they had referred it to the Messenger or to those charged with authority among them, the proper investigators would have understood it from them (directly). Had it not been for the Grace and Mercy of Allah upon you, you would have followed Shaitan (Satan), save a few of you.

(112) when you are greeted with a greeting, greet in return with what is better than it, or (at least) return it equally. Certainly, Allah is Ever a Careful Account Taker of all things.

(113) O you who believe! when you go (to fight) in the Cause of Allah, verify (the truth), and say not to anyone who greets you (by embracing Islam): "You are not a believer"; seeking the perishable goods of the worldly life. There are much more profits and booties with Allah. Even as he is now, so were you yourselves before till Allah conferred on you His Favours (i.e. guided you to Islam), therefore, be cautious in discrimination. Allah is Ever Well-Aware of what you do.

(114) And when you (Muslims) travel in the land, there is no sin on you if you shorten As-Salat (the prayer) if you fear that the disbelievers may put you in trial (attack you etc.), verily, the disbelievers are ever unto you open enemies.

(115) when you (O Messenger Muhammad صلى الله عليه وسلم) are among them, and lead them in As-Salat (the prayer), let one party of them stand up [in Salat (prayer)] with you taking their arms with them; when they finish their prostrations, let them take their positions in the rear and let the other party come up which have not yet prayed, and let them pray with you taking all the precautions and bearing arms. Those who disbelieve wish, if you were negligent of your arms and your baggage, to attack you in a single rush, but there is no sin on you if you put away your arms because of the inconvenience of rain or because you are ill, but take every precaution for yourselves. Verily, Allah has prepared a humiliating torment for the disbelievers.

(116) when you have finished As-Salat (the congregational prayer), remember Allah standing, sitting down, and (lying down) on your sides, but when you are free from danger, perform As-Salat (Iqamat-as-Salat). Verily, As-Salat (the prayer) is enjoined on the believers at fixed hours.

(117) They may hide (their crimes) from men, but they cannot hide (them) from Allah; for He is with them (by His Knowledge), when they plot by night in words that He does not approve. And Allah ever encompasses what they do.

(118) And it has already been revealed to you in the Book (this Qur'an) that when you hear the Verses of Allah being denied and mocked at, then sit not with them, until they engage in a talk other than that; (but if you stayed with them) certainly in that case you would be like them. Surely, Allah will collect the hypocrites and disbelievers all together in Hell.

(119) Verily, the hypocrites seek to deceive Allah, but it is He Who deceives them. And when they stand up for As-Salat (the prayer), they stand with laziness and to be seen of men, and they do not remember Allah but little.

(120) The people of the Scripture (Jews) ask you to cause a book to descend upon them from heaven. Indeed they asked Musa (Moses) for even greater than that, when they said: "Show us Allah in public," but they were struck with thunderclap and lightning for their wickedness. Then they worshipped the calf even after clear proofs, evidence, and signs had come to them. (Even) so We forgave them. And We gave Musa (Moses) a clear proof of authority.
