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

(121) O you who believe! Fulfil (your) obligations. Lawful to you (for food) are all the beasts of cattle except that which will be announced to you (herein), game (also) being unlawful when you assume Ihram for Hajj or 'Umrah (pilgrimage). Verily, Allah commands that which He wills.

(122) O you who believe! Violate not the sanctity of the Symbols of Allah, nor of the Sacred Month, nor of the animals brought for sacrifice, nor the garlanded people or animals , and others nor the people coming to the Sacred House (Makkah), seeking the bounty and good pleasure of their Lord. But when you finish the Ihram (of Hajj or 'Umrah ), you may hunt, and let not the hatred of some people in (once) stopping you from Al-Masjid-Al-Haram (at Makkah) lead you to transgression (and hostility on your part). Help you one another in Al-Birr and At-Taqwa (virtue, righteousness and piety); but do not help one another in sin and transgression. And fear Allah. Verily, Allah is Severe in punishment.

(123) Made lawful to you this day are At-Tayyibat [all kinds of Halal (lawful) foods, which Allah has made lawful (meat of slaughtered eatable animals, milk products, fats, vegetables and fruits)]. The food (slaughtered cattle, eatable animals) of the people of the Scripture (Jews and Christians) is lawful to you and yours is lawful to them. (Lawful to you in marriage) are chaste women from the believers and chaste women from those who were given the Scripture (Jews and Christians) before your time when you have given their due Mahr (bridal-money given by the husband to his wife at the time of marriage), desiring chastity (i.e. taking them in legal wedlock) not committing illegal sexual intercourse, nor taking them as girl-friends. And whosoever disbelieves in Faith [i.e. in the Oneness of Allah and in all the other Articles of Faith i.e. His (Allah's) Angels, His Holy Books, His Messengers, the Day of Resurrection and Al-Qadar (Divine Preordainments)], then fruitless is his work; and in the Hereafter he will be among the losers.

(124) O you who believe! when you intend to offer As-Salat (the prayer), wash your faces and your hands (forearms) up to the elbows, rub (by passing wet hands over) your heads, and (wash) your feet up to ankles . If you are in a state of Janaba (i.e. after a sexual discharge), purify yourselves (bathe your whole body). But if you are ill or on a journey, or any of you comes after answering the call of nature, or you have been in contact with women (i.e. sexual intercourse), and you find no water, then perform Tayammum with clean earth and rub therewith your faces and hands. Allah does not want to place you in difficulty, but He wants to purify you, and to complete His Favour to you that you may be thankful.

(125) And remember Allah's Favour to you and His Covenant with which He bound you when you said: "We hear and we obey." And fear Allah. Verily, Allah is All-Knower of that which is in (the secrets of your) breasts.

(126) O you who believe! Remember the Favour of Allah unto you when some people desired (made a plan) to stretch out their hands against you, but (Allah) held back their hands from you. So fear Allah. And in Allah let the believers put their trust.

(127) And from those who call themselves Christians, We took their covenant, but they have abandoned a good part of the Message that was sent to them. So We planted amongst them enmity and hatred till the Day of Resurrection (when they discarded Allah's Book, disobeyed Allah's Messengers and His Orders and transgressed beyond bounds in Allah's disobedience); and Allah will inform them of what they used to do.

(128) And (remember) when Musa (Moses) said to his people: "O my people! Remember the Favour of Allah to you when He made Prophets among you, made you kings and gave you what He had not given to any other among the 'Alamin (mankind and jinn, in the past)."

(129) They said: "O Musa (Moses)! In it (this holy land) are a people of great strength, and we shall never enter it till they leave it; when they leave, then we will enter."

(130) Two men of those who feared (Allah and) on whom Allah had bestowed His Grace (they were يوشع وكالب Yusha' and Kalab) said: "Assault them through the gate; for when you are in, victory will be yours; and put your trust in Allah if you are believers indeed."
