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

(51) "On the Day when every soul will be confronted with all the good it has done, and all the evil it has done, it will wish there were a great distance between it and its evil. But Allah cautions you (To remember) Himself. And Allah is full of kindness to those that serve Him."

(52) when she was delivered, she said: "O my Lord! Behold! I am delivered of a female child!"- and Allah knew best what she brought forth- "And no wise is the male Like the female. I have named her Mary, and I commend her and her offspring to Thy protection from the Evil One, the Rejected."

(53) Right graciously did her Lord accept her: He made her grow in purity and beauty: To the care of Zakariya was she assigned. Every time that he entered (Her) chamber to see her, He found her supplied with sustenance. He said: "O Mary! whence (comes) this to you?" She said: "From Allah: for Allah Provides sustenance to whom He pleases without measure."

(54) This is part of the tidings of the things unseen, which We reveal unto thee (O Messenger!) by inspiration: Thou wast not with them when they cast lots with arrows, as to which of them should be charged with the care of Mary: Nor wast thou with them when they disputed (the point).

(55) She said: "O my Lord! How shall I have a son when no man hath touched me?" He said: "Even so: Allah createth what He willeth: when He hath decreed a plan, He but saith to it, 'Be,' and it is!

(56) when Jesus found Unbelief on their part He said: "Who will be My helpers to (the work of) Allah?" Said the disciples: "We are Allah's helpers: We believe in Allah, and do thou bear witness that we are Muslims.

(57) Ye People of the Book! Why dispute ye about Abraham, when the Law and the Gospel Were not revealed Till after him? Have ye no understanding?

(58) Say: "O People of the Book! Why reject ye the Signs of Allah, when Allah is Himself witness to all ye do?"

(59) On the Day when some faces will be (lit up with) white, and some faces will be (in the gloom of) black: To those whose faces will be black, (will be said): "Did ye reject Faith after accepting it? Taste then the penalty for rejecting Faith."

(60) Shame is pitched over them (Like a tent) wherever they are found, except when under a covenant (of protection) from Allah and from men; they draw on themselves wrath from Allah, and pitched over them is (the tent of) destitution. This because they rejected the Signs of Allah, and slew the prophets in defiance of right; this because they rebelled and transgressed beyond bounds.
