The word(s) "war" appears 551 time(s) in 494 verse(s) in Quran in Mohsin Khan translation.

(121) Say to those who have disbelieved, if they cease (from disbelief), their past will be forgiven. But if they return (thereto), then the examples of those (punished) before them have already preceded (as a warning).

(122) And know that whatever of war-booty that you may gain, verily one-fifth (1/5th) of it is assigned to Allah, and to the Messenger, and to the near relatives [of the Messenger (Muhammad صلى الله عليه وسلم)], (and also) the orphans, Al-Masakin (the poor) and the wayfarer, if you have believed in Allah and in that which We sent down to Our slave (Muhammad صلى الله عليه وسلم) on the Day of criterion (between right and wrong), the Day when the two forces met (the battle of Badr); And Allah is able to do all things.

(123) "This is because of that which your hands had forwarded. And verily, Allah is not unjust to His slaves."

(124) So if you gain the mastery over them in war, punish them severely in order to disperse those who are behind them, so that they may learn a lesson.

(125) And make ready against them all you can of power, including steeds of war (tanks, planes, missiles, artillery) to threaten the enemy of Allah and your enemy, and others besides whom, you may not know but whom Allah does know. And whatever you shall spend in the Cause of Allah shall be repaid unto you, and you shall not be treated unjustly.

(126) It is not for a Prophet that he should have prisoners of war (and free them with ransom) until he had made a great slaughter (among his enemies) in the land. You desire the good of this world (i.e. the money of ransom for freeing the captives), but Allah desires (for you) the Hereafter. And Allah is All-Mighty, All-Wise.

(127) So enjoy what you have gotten of booty in war, lawful and good, and be afraid of Allah. Certainly, Allah is Oft-Forgiving, Most Merciful.

(128) And those who disbelieve are allies of one another, (and) if you (Muslims of the whole world collectively) do not do so [i.e. become allies, as one united block under one Khalifah (a chief Muslim ruler for the whole Muslim world) to make victorious Allah's religion of Islamic Monotheism], there will be Fitnah (wars, battles, polytheism) and oppression on the earth, and a great mischief and corruption (appearance of polytheism).

(129) And those who believed afterwards, and emigrated and strove hard along with you (in the Cause of Allah), they are of you. But kindred by blood are nearer to one another (regarding inheritance) in the decree ordained by Allah. Verily, Allah is the All-Knower of everything.

(130) They will dwell therein forever. Verily, with Allah is a great reward.
