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

(411) when he saw fire, he said to his family: Stop, for surely I see a fire, haply I may bring to you therefrom a live coal or find a guidance at the fire.

(412) So when he came to it, a voice was uttered: O Musa:

(413) when We revealed to your mother what was revealed;

(414) when your sister went and said: Shall I direct you to one who will take charge of him? So We brought you back to your mother, that her eye might be cooled and she should not grieve and you killed a man, then We delivered you from the grief, and We tried you with (a severe) trying. Then you stayed for years among the people of Madyan; then you came hither as ordained, O Musa.

(415) (Musa) said: O Haroun! what prevented you, when you saw them going astray,

(416) On the day when the trumpet shall be blown, and We will gather the guilty, blue-eyed, on that day

(417) We know best what they say, when the fairest of them in course would say: You tarried but a day.

(418) And when We said to the angels: Make obeisance to Adam, they made obeisance, but Iblis (did it not); he refused.

(419) So when they felt Our punishment, lo! they began to fly

(420) And when those who disbelieve see you, they do not take you but for one to be scoffed at: Is this he who speaks of your gods? And they are deniers at the mention of the Beneficent Allah.
