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

(431) On the day when We will roll up heaven like the rolling up of the scroll for writings, as We originated the first creation, (so) We shall reproduce it; a promise (binding on Us); surely We will bring it about.

(432) On the day when you shall see it, every woman giving suck shall quit in confusion what she suckled, and every pregnant woman shall lay down her burden, and you shall see men intoxicated, and they shall not be intoxicated but the chastisement of Allah will be severe.

(433) O people! if you are in doubt about the raising, then surely We created you from dust, then from a small seed, then from a clot, then from a lump of flesh, complete in make and incomplete, that We may make clear to you; and We cause what We please to stay in the wombs till an appointed time, then We bring you forth as babies, then that you may attain your maturity; and of you is he who is caused to die, and of you is he who is brought back to the worst part of life, so that after having knowledge he does not know anything; and you see the earth sterile land, but when We send down on it the water, it stirs and swells and brings forth of every kind a beautiful herbage.

(434) whenever they will desire to go forth from it, from grief, they shall be turned back into it, and taste the chastisement of burning.

(435) And when We assigned to Ibrahim the place of the House, saying: Do not associate with Me aught, and purify My House for those who make the circuit and stand to pray and bow and prostrate themselves.

(436) (To) those whose hearts tremble when Allah is mentioned, and those who are patient under that which afflicts them, and those who keep up prayer, and spend (benevolently) out of what We have given them.

(437) And (as for) the camels, We have made them of the signs of the religion of Allah for you; for you therein is much good; therefore mention the name of Allah on them as they stand in a row, then when they fall down eat of them and feed the poor man who is contented and the beggar; thus have We made them subservient to you, that you may be grateful.

(438) And We did not send before you any apostle or prophet, but when he desired, the Shaitan made a suggestion respecting his desire; but Allah annuls that which the Shaitan casts, then does Allah establish His communications, and Allah is Knowing, Wise,

(439) And when Our clear communications are recited to them you will find denial on the faces of those who disbelieve; they almost spring upon those who recite to them Our communications. Say: Shall I inform you of what is worse than this? The fire; Allah has promised it to those who disbelieve; and how evil the resort!

(440) So We revealed to him, saying: Make the ark before Our eyes and (according to) Our revelation; and when Our command is given and the valley overflows, take into it of every kind a pair, two, and your followers, except those among them against whom the word has gone forth, and do not speak to Me in respect of those who are unjust; surely they shall be drowned.
