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

(381) And remember (Hud) the brother of 'Ad, when he warned his people in Al-Ahqaf (the curved sand-hills in the southern part of Arabian Peninsula). And surely, there have passed away warners before him and after him (saying): "Worship none but Allah; truly, I fear for you the torment of a mighty Day (i.e. the Day of Resurrection)."

(382) Then, when they saw it as a dense cloud coming towards their valleys, they said: "This is a cloud bringing us rain!" Nay, but it is that (torment) which you were asking to be hastened - a wind wherein is a painful torment!

(383) And (remember) when We sent towards you (Muhammad صلى الله عليه وسلم) a group (three to ten persons) of the jinn, (quietly) listening to the Qur'an. When they stood in the presence thereof, they said: "Listen in silence!" And when it was finished, they returned to their people, as warners.

(384) So, when you meet (in fight - Jihad in Allah's Cause) those who disbelieve, smite (their) necks till when you have killed and wounded many of them, then bind a bond firmly (on them, i.e. take them as captives). Thereafter (is the time) either for generosity (i.e. free them without ransom), or ransom (according to what benefits Islam), until the war lays down its burden. Thus [you are ordered by Allah to continue in carrying out Jihad against the disbelievers till they embrace Islam and are saved from the punishment in the Hell-fire or at least come under your protection], but if it had been Allah's Will, He Himself could certainly have punished them (without you). But (He lets you fight) in order to test some of you with others. But those who are killed in the Way of Allah, He will never let their deeds be lost.

(385) So be not weak and ask not for peace (from the enemies of Islam) while you are having the upper hand. Allah is with you, and He will never decrease the reward of your good deeds.

(386) Verily, We have sent you (O Muhammad صلى الله عليه وسلم) as a witness, as a bearer of glad tidings, and as a warner .

(387) Verily, those who give Bai'ah (pledge) to you (O Muhammad صلى الله عليه وسلم) they are giving Bai'ah (pledge) to Allah. The Hand of Allah is over their hands. Then whosoever breaks his pledge, breaks it only to his own harm; and whosoever fulfils what he has covenanted with Allah, He will bestow on him a great reward.

(388) Those of the bedouins who lagged behind will say to you: "Our possessions and our families occupied us, so ask forgiveness for us." They say with their tongues what is not in their hearts. Say: "Who then has any power at all (to intervene) on your behalf with Allah, if He intends you hurt or intends you benefit? Nay, but Allah is Ever All-Aware of what you do.

(389) Say (O Muhammad صلى الله عليه وسلم) to the bedouins who lagged behind: "You shall be called to fight against a people given to great warfare, then you shall fight them, or they shall surrender. Then if you obey, Allah will give you a fair reward; but if you turn away as you did turn away before, He will punish you with a painful torment."

(390) Indeed, Allah was pleased with the believers when they gave the Bai'ah (pledge) to you (O Muhammad صلى الله عليه وسلم) under the tree: He knew what was in their hearts, and He sent down As-Sakinah (calmness and tranquillity) upon them, and He rewarded them with a near victory.
