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

(251) They will excuse themselves to you when you go back to them. Say: Urge no excuse, by no means will we believe you; indeed Allah has informed us of matters relating to you; and now Allah and His Apostle will see your doings, then you shall be brought back to the Knower of the unseen and the seen, then He will inform you of what you did.

(252) They will swear to you by Allah when you return to them so that you may turn aside from them; so do turn aside from them; surely they are unclean and their abode is hell; a recompense for what they earned.

(253) And Ibrahim asking forgiveness for his sire was only owing to a promise which he had made to him; but when it became clear to him that he was an enemy of Allah, he declared himself to be clear of him; most surely Ibrahim was very tender-hearted forbearing.

(254) And it does not beseem the believers that they should go forth all together; why should not then a company from every party from among them go forth that they may apply themselves to obtain understanding in religion, and that they may warn their people when they come back to them that they may be cautious?

(255) And whenever a chapter is revealed, there are some of them who say: Which of you has it strengthened in faith? Then as for those who believe, it strengthens them in faith and they rejoice.

(256) And whenever a chapter is revealed, they cast glances at one another: Does any one see you? Then they turn away: Allah has turned away their hearts because they are a people who do not understand.

(257) And when affliction touches a man, he calls on Us, whether lying on his side or sitting or standing; but when We remove his affliction from him, he passes on as though he had never called on Us on account of an affliction that touched him; thus that which they do is made fair-seeming to the extravagant.

(258) And certainly We did destroy generations before you when they were unjust, and their apostles had come to them with clear arguments, and they would not believe; thus do We recompense the guilty people.

(259) And when Our clear communications are recited to them, those who hope not for Our meeting say: Bring a Quran other than this or change it. Say: It does not beseem me that I should change it of myself; I follow naught but what is revealed to me; surely I fear, if I disobey my Lord, the punishment of a mighty day.

(260) And when We make people taste of mercy after an affliction touches them, lo! they devise plans against Our communication. Say: Allah is quicker to plan; surely Our apostles write down what you plan.
