The word(s) "war" appears 766 time(s) in 668 verse(s) in Quran in Muhammad Pickthal translation.

(531) And on the day when those who disbelieve are exposed to the Fire (it will be said): Ye squandered your good things in the life of the world and sought comfort therein. Now this day ye are rewarded with the doom of ignominy because ye were disdainful in the land without a right, and because ye used to transgress.

(532) And make mention (O Muhammad) of the brother of A'ad when he warned his folk among the wind-curved sandhills - and verily warners came and went before and after him - saying: Serve none but Allah. Lo! I fear for you the doom of a tremendous Day.

(533) Then, when they beheld it as a dense cloud coming toward their valleys, they said: Here is a cloud bringing us rain. Nay, but it is that which ye did seek to hasten, a wind wherein is painful torment,

(534) Destroying all things by commandment of its Lord. And morning found them so that naught could be seen save their dwellings. Thus do We reward the guilty folk.

(535) And when We inclined toward thee (Muhammad) certain of the jinn, who wished to hear the Qur'an and, when they were in its presence, said: Give ear! and, when it was finished, turned back to their people, warning.

(536) Now when ye meet in battle those who disbelieve, then it is smiting of the necks until, when ye have routed them, then making fast of bonds; and afterward either grace or ransom till the war lay down its burdens. That (is the ordinance). And if Allah willed He could have punished them (without you) but (thus it is ordained) that He may try some of you by means of others. And those who are slain in the way of Allah, He rendereth not their actions vain.

(537) Await they aught save the Hour, that it should come upon them unawares? And the beginnings thereof have already come. But how, when it hath come upon them, can they take their warning?

(538) And those who believe say: If only a surah were revealed! But when a decisive surah is revealed and war is mentioned therein, thou seest those in whose hearts is a disease looking at thee with the look of men fainting unto death. Therefor woe unto them!

(539) So do not falter and cry out for peace when ye (will be) the uppermost, and Allah is with you, and He will not grudge (the reward of) your actions.

(540) The life of the world is but a sport and a pastime. And if ye believe and ward off (evil). He will give you your wages, and will not ask of you your wordly wealth.
