The word(s) "when" appears 916 time(s) in 828 verse(s) in Quran in Mohsin Khan translation.

(181) And it is He Who sends the winds as heralds of glad tidings, going before His Mercy (rain). Till when they have carried a heavy-laden cloud, We drive it to a land that is dead, then We cause water (rain) to descend thereon. Then We produce every kind of fruit therewith. Similarly, We shall raise up the dead, so that you may remember or take heed.

(182) And remember when He made you successors after 'Ad (people) and gave you habitations in the land, you build for yourselves palaces in plains, and carve out homes in the mountains. So remember the graces (bestowed upon you) from Allah, and do not go about making mischief on the earth."

(183) And (remember) Lut (Lot), when he said to his people: "Do you commit the worst sin such as none preceding you has committed in the 'Alamin (mankind and jinn)?

(184) "And sit not on every road, threatening, and hindering from the Path of Allah those who believe in Him, and seeking to make it crooked. And remember when you were but few, and He multiplied you. And see what was the end of the Mufsidun (mischief-makers, corrupters, liars).

(185) He [Musa (Moses)] said: "Throw you (first)." So when they threw, they bewitched the eyes of the people, and struck terror into them, and they displayed a great magic.

(186) "And you take vengeance on us only because we believed in the Ayat (proofs, evidence, lessons, signs, etc.) of our Lord when they reached us! Our Lord! pour out on us patience, and cause us to die as Muslims."

(187) But whenever good came to them, they said: "Ours is this." And if evil afflicted them, they ascribed it to evil omens connected with Musa (Moses) and those with him. Be informed! Verily, their evil omens are with Allah but most of them know not.

(188) And when the punishment fell on them they said: "O Musa (Moses)! Invoke your Lord for us because of His Promise to you. If you remove the punishment from us, we indeed shall believe in you, and we shall let the Children of Israel go with you."

(189) But when We removed the punishment from them to a fixed term, which they had to reach, behold! they broke their word!

(190) And (remember) when We rescued you from Fir'aun's (Pharaoh) people, who were afflicting you with the worst torment, killing your sons and letting your women live. And in that was a great trial from your Lord.
