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

(331) And the king said: Bring him unto me. And when the messenger came unto him, he (Joseph) said: Return unto thy lord and ask him what was the case of the women who cut their hands. Lo! my Lord knoweth their guile.

(332) He (the king) (then sent for those women and) said: What happened when ye asked an evil act of Joseph? They answered: Allah Blameless! We know no evil of him. Said the wife of the ruler: Now the truth is out. I asked of him an evil act, and he is surely of the truthful.

(333) And the king said: Bring him unto me that I may attach him to my person. And when he had talked with him he said: Lo! thou art to-day in our presence established and trusted.

(334) And when he provided them with their provision he said: Bring unto me a brother of yours from your father. See ye not that I fill up the measure and I am the best of hosts?

(335) He said unto his young men: Place their merchandise in their saddlebags, so that they may know it when they go back to their folk, and so will come again.

(336) So when they went back to their father they said: O our father! The measure is denied us, so send with us our brother that we may obtain the measure, surely we will guard him well.

(337) And when they opened their belongings they discovered that their merchandise had been returned to them. They said: O our father! What (more) can we ask? Here is our merchandise returned to us. We shall get provision for our folk and guard our brother, and we shall have the extra measure of a camel (load). This (that we bring now) is a light measure.

(338) He said: I will not send him with you till ye give me an undertaking in the name of Allah that ye will bring him back to me, unless ye are surrounded. And when they gave him their undertaking he said: Allah is the Warden over what we say.

(339) And when they entered in the manner which their father had enjoined, it would have naught availed them as against Allah; it was but a need of Jacob's soul which he thus satisfied; and lo! he was a lord of knowledge because We had taught him; but most of mankind know not.

(340) And when they went in before Joseph, he took his brother unto him, saying: Lo! I, even I, am thy brother, therefore sorrow not for what they did.
