The word(s) "when" appears 708 time(s) in 647 verse(s) in Quran in Abdullah Yusuf Ali translation.

(21) So from whencesoever Thou startest forth, turn Thy face in the direction of the sacred Mosque; and wheresoever ye are, Turn your face thither: that there be no ground of dispute against you among the people, except those of them that are bent on wickedness; so fear them not, but fear Me; and that I may complete My favours on you, and ye May (consent to) be guided;

(22) Who say, when afflicted with calamity: "To Allah We belong, and to Him is our return":-

(23) when it is said to them: "Follow what Allah hath revealed:" They say: "Nay! we shall follow the ways of our fathers." What! even though their fathers Were void of wisdom and guidance?

(24) It is prescribed, when death approaches any of you, if he leave any goods that he make a bequest to parents and next of kin, according to reasonable usage; this is due from the Allah-fearing.

(25) when My servants ask thee concerning Me, I am indeed close (to them): I listen to the prayer of every suppliant when he calleth on Me: Let them also, with a will, Listen to My call, and believe in Me: That they may walk in the right way.

(26) And complete the Hajj or 'umra in the service of Allah. But if ye are prevented (From completing it), send an offering for sacrifice, such as ye may find, and do not shave your heads until the offering reaches the place of sacrifice. And if any of you is ill, or has an ailment in his scalp, (Necessitating shaving), (He should) in compensation either fast, or feed the poor, or offer sacrifice; and when ye are in peaceful conditions (again), if any one wishes to continue the 'umra on to the hajj, He must make an offering, such as he can afford, but if he cannot afford it, He should fast three days during the hajj and seven days on his return, Making ten days in all. This is for those whose household is not in (the precincts of) the Sacred Mosque. And fear Allah, and know that Allah Is strict in punishment.

(27) It is no crime in you if ye seek of the bounty of your Lord (during pilgrimage). Then when ye pour down from (Mount) Arafat, celebrate the praises of Allah at the Sacred Monument, and celebrate His praises as He has directed you, even though, before this, ye went astray.

(28) Then pass on at a quick pace from the place whence it is usual for the multitude so to do, and ask for Allah's forgiveness. For Allah is Oft-forgiving, Most Merciful.

(29) So when ye have accomplished your holy rites, celebrate the praises of Allah, as ye used to celebrate the praises of your fathers,- yea, with far more Heart and soul. There are men who say: "Our Lord! Give us (Thy bounties) in this world!" but they will have no portion in the Hereafter.

(30) when he turns his back, His aim everywhere is to spread mischief through the earth and destroy crops and cattle. But Allah loveth not mischief.
