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

(551) For surely you cannot, make the dead to hear and you cannot make the deaf to hear the call, when they show their backs and turn away.

(552) And at the time when the hour shall come, the guilty shall swear (that) they did not tarry but an hour; thus are they ever turned away.

(553) And when Our communications are recited to him, he turns back proudly, as if he had not heard them, as though in his ears were a heaviness, therefore announce to him a painful chastisement.

(554) And when Luqman said to his son while he admonished him: O my son! do not associate aught with Allah; most surely polytheism is a grievous iniquity--

(555) And when it is said to them: Follow what Allah has revealed, they say: Nay, we follow that on which we found our fathers. What! though the Shaitan calls them to the chastisement of the burning fire!

(556) And when a wave like mountains covers them they call upon Allah, being sincere to Him in obedience, but when He brings them safe to the land, some of them follow the middle course; and none denies Our signs but every perfidious, ungrateful one.

(557) O people! guard against (the punishment of) your Lord and dread the day when a father shall not make any satisfaction for his son, nor shall the child be the maker of any satisfaction for his father; surely the promise of Allah is true, therefore let not this world's life deceive you, nor let the archdeceiver deceive you in respect of Allah.

(558) And they say: What! when we have become lost in the earth, shall we then certainly be in a new creation? Nay! they are disbelievers in the meeting of their Lord.

(559) And could you but see when the guilty shall hang down their heads before their Lord: Our Lord! we have seen and we have heard, therefore send us back, we will do good; surely (now) we are certain.

(560) Only they believe in Our communications who, when they are reminded of them, fall down in prostration and celebrate the praise of their Lord, and they are not proud.
