The word(s) "when" appears 1006 time(s) in 918 verse(s) in Quran in Muhammad Pickthal translation.

(101) And when thou settedst forth at daybreak from thy housefolk to assign to the believers their positions for the battle, Allah was Hearer, Knower.

(102) when two parties of you almost fell away, and Allah was their Protecting Friend. In Allah let believers put their trust.

(103) Allah had already given you the victory at Badr, when ye were contemptible. So observe your duty to Allah in order that ye may be thankful.

(104) when thou didst say unto the believers: Is it not sufficient for you that your Lord should support you with three thousand angels sent down (to your help)?

(105) And those who, when they do an evil thing or wrong themselves, remember Allah and implore forgiveness for their sins - Who forgiveth sins save Allah only? - and will not knowingly repeat (the wrong) they did.

(106) Muhammad is but a messenger, messengers (the like of whom) have passed away before him. Will it be that, when he dieth or is slain, ye will turn back on your heels? He who turneth back on his heels doth no hurt to Allah, and Allah will reward the thankful.

(107) Allah verily made good His promise unto you when ye routed them by His leave, until (the moment) when your courage failed you, and ye disagreed about the order and ye disobeyed, after He had shown you that for which ye long. Some of you desired the world, and some of you desired the Hereafter. Therefore He made you flee from them, that He might try you. Yet now He hath forgiven you. Allah is a Lord of Kindness to believers.

(108) when ye climbed (the hill) and paid no heed to anyone, while the messenger, in your rear, was calling you (to fight). Therefor He rewarded you grief for (his) grief, that (He might teach) you not to sorrow either for that which ye missed or for that which befell you. Allah is Informed of what ye do.

(109) Lo! those of you who turned back on the day when the two hosts met, Satan alone it was who caused them to backslide, because of some of that which they have earned. Now Allah hath forgiven them. Lo! Allah is Forgiving, Clement.

(110) What though ye be slain or die, when unto Allah ye are gathered?
