The word(s) "when" appears 1006 time(s) in 918 verse(s) in Quran in Muhammad Pickthal translation.

(321) when they said: Verily Joseph and his brother are dearer to our father than we are, many though we be. Lo! our father is in plain aberration.

(322) They said: O our father! Why wilt thou not trust us with Joseph, when lo! we are good friends to him?

(323) They said: If the wolf should devour him when we are (so strong) a band, then surely we should have already perished.

(324) Then, when they led him off, and were of one mind that they should place him in the depth of the pit, We inspired in him: Thou wilt tell them of this deed of theirs when they know (thee) not.

(325) Saying: O our father! We went racing one with another, and left Joseph by our things, and the wolf devoured him, and thou believest not our saying even when we speak the truth.

(326) And And when he reached his prime We gave him wisdom and knowledge. Thus We reward the good.

(327) So when he saw his shirt torn from behind, he said: Lo! this is of the guile of you women. Lo! the guile of you is very great.

(328) And when she heard of their sly talk, she sent to them and prepared for them a cushioned couch (to lie on at the feast) and gave to every one of them a knife and said (to Joseph): Come out unto them! And when they saw him they exalted him and cut their hands, exclaiming: Allah Blameless! This is no a human being. This is not other than some gracious angel.

(329) (And when he came to Joseph in the prison, he exclaimed): Joseph! O thou truthful one! Expound for us the seven fat kine which seven lean were eating and the seven green ears of corn and other (seven) dry, that I may return unto the people, so that they may know.

(330) Then, after that, will come a year when the people will have plenteous crops and when they will press (wine and oil).
