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

(81) She said: "O my Lord! How shall I have a son when no man has touched me." He said: "So (it will be) for Allah creates what He wills. when He has decreed something, He says to it only: "Be!" - and it is.

(82) Then when 'Îsa (Jesus) came to know of their disbelief, he said: "Who will be my helpers in Allah's Cause?" Al-Hawariyyun (the disciples) said: "We are the helpers of Allah; we believe in Allah, and bear witness that we are Muslims (i.e. we submit to Allah)."

(83) And (remember) when Allah said: "O 'Îsa (Jesus)! I will take you and raise you to Myself and clear you [of the forged statement that 'Îsa (Jesus) is Allah's son] of those who disbelieve, and I will make those who follow you (Monotheists, who worship none but Allah) superior to those who disbelieve [in the Oneness of Allah, or disbelieve in some of His Messengers, e.g. Muhammad صلى الله عليه وسلم, 'Îsa (Jesus), Musa (Moses), etc., or in His Holy Books, e.g. the Taurat (Torah), the Injeel (Gospel), the Qur'an] till the Day of Resurrection . Then you will return to Me and I will judge between you in the matters in which you used to dispute."

(84) And (remember) when Allah took the Covenant of the Prophets, saying: "Take whatever I gave you from the Book and Hikmah (understanding of the Laws of Allah), and afterwards there will come to you a Messenger (Muhammad صلى الله عليه وسلم) confirming what is with you; you must, then, believe in him and help him." Allah said: "Do you agree (to it) and will you take up My Covenant (which I conclude with you)?" They said: "We agree." He said: "Then bear witness; and I am with you among the witnesses (for this)."

(85) On the Day (i.e. the Day of Resurrection) when some faces will become white and some faces will become black; as for those whose faces will become black (to them will be said): "Did you reject Faith after accepting it? Then taste the torment (in Hell) for rejecting Faith."

(86) Indignity is put over them wherever they may be, except when under a covenant (of protection) from Allah, and from men; they have drawn on themselves the Wrath of Allah, and destruction is put over them. This is because they disbelieved in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah and killed the Prophets without right. This is because they disobeyed (Allah) and used to transgress beyond bounds (in Allah's disobedience, crimes and sins).

(87) Lo! You are the ones who love them but they love you not, and you believe in all the Scriptures [i.e. you believe in the Taurat (Torah) and the Injeel (Gospel), while they disbelieve in your Book, the Qur'an]. And when they meet you, they say, "We believe." But when they are alone, they bite the tips of their fingers at you in rage. Say: "Perish in your rage. Certainly, Allah knows what is in the breasts (all the secrets)."

(88) And (remember) when you (Muhammad صلى الله عليه وسلم) left your household in the morning to post the believers at their stations for the battle (of Uhud). And Allah is All-Hearer, All-Knower.

(89) when two parties from among you were about to lose heart, but Allah was their Wali (Supporter and Protector). And in Allah should the believers put their trust.

(90) And Allah has already made you victorious at Badr, when you were a weak little force. So fear Allah much that you may be grateful.
