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

(321) Verily We have sent you with the truth, a bearer of glad tidings and a warner. And there never was a nation but a warner had passed among them.

(322) And what We have revealed to you (O Muhammad صلى الله عليه وسلم), of the Book (the Qur'an), it is the (very) truth [that you (Muhammad صلى الله عليه وسلم) and your followers must act on its instructions], confirming that which was (revealed) before it. Verily! Allah is indeed All-Aware, and All-Seer of His slaves.

(323) Therein they will cry: "Our Lord! Bring us out, we shall do righteous good deeds, not (the evil deeds) that we used to do." (Allah will reply): "Did We not give you lives long enough, so that whosoever would receive admonition could receive it? And the warner came to you. So taste you (the evil of your deeds). For the Zalimun (polytheists and wrong-doers) there is no helper."

(324) And they swore by Allah their most binding oath that if a warner came to them, they would be more guided than any of the nations (before them); yet when a warner (Muhammad صلى الله عليه وسلم) came to them, it increased in them nothing but flight (from the truth)

(325) In order that you may warn a people whose forefathers were not warned, so they are heedless.

(326) It is the same to them whether you warn them or you warn them not, they will not believe.

(327) You can only warn him who follows the Reminder (the Qur'an), and fears the Most Gracious (Allah) unseen. Bear you to such one the glad tidings of forgiveness, and a generous reward (i.e. Paradise).

(328) And put forward to them a similitude: the (story of the) dwellers of the town, [it is said that the town was Antioch (Antakiya)], when there came Messengers to them.

(329) And if it had been Our Will, We could have transformed them (into animals or lifeless objects) in their places. Then they would have been unable to go forward (move about) nor they could have turned back.

(330) That he or it (Muhammad صلى الله عليه وسلم or the Qur'an) may give warning to him who is living (a healthy minded - the believer), and that Word (charge) may be justified against the disbelievers (dead, as they reject the warnings).
