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

(691) when those who disbelieved harbored in their hearts (feelings of) disdain, the disdain of (the days of) ignorance, but Allah sent down His tranquillity on His Apostle and on the believers, and made them keep the word of guarding (against evil), and they were entitled to it and worthy of it; and Allah is Cognizant of all things.

(692) What! when we are dead and have become dust? That is afar (from probable) return.

(693) Nay, they rejected the truth when it came to them, so they are (now) in a state of confusion.

(694) when the two receivers receive, sitting on the right and on the left.

(695) And listen on the day when the crier shall cry from a near place

(696) The day when they shall hear the cry in truth; that is the day of coming forth.

(697) They ask: when is the day of judgment?

(698) when they entered upon him, they said: Peace. Peace, said he, a strange people.

(699) And in Musa: when We sent him to Firon with clear authority.

(700) And in Ad: when We sent upon them the destructive wind.
