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

(431) And (remember) when We showed Ibrahim (Abraham) the site of the (Sacred) House (the Ka'bah at Makkah) (saying): "Associate not anything (in worship) with Me, [La ilaha illallah (none has the right to be worshipped but Allah) - Islamic Monotheism], and sanctify My House for those who circumambulate it, and those who stand up (for prayer), and those who bow (submit themselves with humility and obedience to Allah), and make prostration (in prayer);"

(432) Whose hearts are filled with fear when Allah is mentioned and As-Sabirun [who patiently bear whatever may befall them (of calamities)]; and who perform As-Salat (Iqamat-as-Salat), and who spend (in Allah's Cause) out of what We have provided them.

(433) And the Budn (cows, oxen, or camels driven to be offered as sacrifices by the pilgrims at the sanctuary of Makkah) We have made them for you as among the Symbols of Allah, wherein you have much good. So mention the Name of Allah over them when they are drawn up in lines (for sacrifice). Then, when they are down on their sides (after slaughter), eat thereof, and feed the poor who does not ask (men), and the beggar who asks (men). Thus have We made them subject to you that you may be grateful.

(434) Never did We send a Messenger or a Prophet before you but when he did recite the revelation or narrated or spoke, Shaitan (Satan) threw (some falsehood) in it. But Allah abolishes that which Shaitan (Satan) throws in. Then Allah establishes His Revelations. And Allah is All-Knower, All-Wise:

(435) And when Our Clear Verses are recited to them, you will notice a denial on the faces of the disbelievers! They are nearly ready to attack with violence those who recite Our Verses to them. Say: "Shall I tell you of something worse than that? The Fire (of Hell) which Allah has promised to those who disbelieved, and worst indeed is that destination!"

(436) So We revealed to him (saying): "Construct the ship under Our Eyes and under Our Revelation (guidance). Then, when Our Command comes, and water gushes forth from the oven, take on board of each kind two (male and female), and your family, except those thereof against whom the Word has already gone forth. And address Me not in favour of those who have done wrong. Verily, they are to be drowned.

(437) And when you have embarked on the ship, you and whoever is with you, then say: "All the praises and thanks be to Allah, Who has saved us from the people who are Zalimun (i.e. oppressors, wrong-doers, polytheists, those who join others in worship with Allah).

(438) "Does he promise you that when you have died and have become dust and bones, you shall come out alive (resurrected)?

(439) Until when We seize those of them who lead a luxurious life with punishment: behold they make humble invocation with a loud voice.

(440) Until, when We open for them the gate of severe punishment, then lo! they will be plunged into destruction with deep regrets, sorrows and in despair.
