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

(381) Say: None in the heavens or on earth, except Allah, knows what is hidden: nor can they perceive when they shall be raised up (for Judgment).

(382) The Unbelievers say: "What! when we become dust,- we and our fathers,- shall we really be raised (from the dead)?

(383) They also say: "when will this promise (come to pass)? (Say) if ye are truthful."

(384) Truly thou canst not cause the dead to listen, nor canst thou cause the deaf to hear the call, (especially) when they turn back in retreat.

(385) And when the Word is fulfilled against them (the unjust), we shall produce from the earth a beast to (face) them: He will speak to them, for that mankind did not believe with assurance in Our Signs.

(387) So We sent this inspiration to the mother of Moses: "Suckle (thy child), but when thou hast fears about him, cast him into the river, but fear not nor grieve: for We shall restore him to thee, and We shall make him one of Our messengers."

(388) when he reached full age, and was firmly established (in life), We bestowed on him wisdom and knowledge: for thus do We reward those who do good.

(389) And he entered the city at a time when its people were not watching: and he found there two men fighting,- one of his own religion, and the other, of his foes. Now the man of his own religion appealed to him against his foe, and Moses struck him with his fist and made an end of him. He said: "This is a work of Evil (Satan): for he is an enemy that manifestly misleads!"

(390) So he saw the morning in the city, looking about, in a state of fear, when behold, the man who had, the day before, sought his help called aloud for his help (again). Moses said to him: "Thou art truly, it is clear, a quarrelsome fellow!"
