The word(s) "preparation" appears 3 time(s) in 3 verse(s) in Quran in Mohsin Khan translation.

(1) And if they had intended to march out, certainly, they would have made some preparation for it; but Allah was averse to their being sent forth, so He made them lag behind, and it was said (to them), "Sit you among those who sit (at home)."

(2) O you who believe! Enter not the Prophet's houses, unless permission is given to you for a meal, (and then) not (so early as) to wait for its preparation. But when you are invited, enter, and when you have taken your meal, disperse without sitting for a talk. Verily, such (behaviour) annoys the Prophet, and he is shy of (asking) you (to go); but Allah is not shy of (telling you) the truth. And when you ask (his wives) for anything you want, ask them from behind a screen: that is purer for your hearts and for their hearts. And it is not (right) for you that you should annoy Allah's Messenger, nor that you should ever marry his wives after him (his death). Verily, with Allah that shall be an enormity.

(3) Obedience (to Allah) and good words (were better for them). And when the matter (preparation for Jihad ) is resolved on, then if they had been true to Allah, it would have been better for them.
