The word(s) "war" appears 438 time(s) in 398 verse(s) in Quran in Saheeh International translation.

(1) Indeed, those who disbelieve - it is all the same for them whether you warn them or do not warn them - they will not believe.

(2) And [recall] when We said, "Enter this city and eat from it wherever you will in [ease and] abundance, and enter the gate bowing humbly and say, 'Relieve us of our burdens.' We will [then] forgive your sins for you, and We will increase the doers of good [in goodness and reward]."

(3) Indeed, those who believed and those who were Jews or Christians or Sabeans [before Prophet Muhammad] - those [among them] who believed in Allah and the Last Day and did righteousness - will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve.

(4) Then your hearts became hardened after that, being like stones or even harder. For indeed, there are stones from which rivers burst forth, and there are some of them that split open and water comes out, and there are some of them that fall down for fear of Allah. And Allah is not unaware of what you do.

(5) Then, you are those [same ones who are] killing one another and evicting a party of your people from their homes, cooperating against them in sin and aggression. And if they come to you as captives, you ransom them, although their eviction was forbidden to you. So do you believe in part of the Scripture and disbelieve in part? Then what is the recompense for those who do that among you except disgrace in worldly life; and on the Day of Resurrection they will be sent back to the severest of punishment. And Allah is not unaware of what you do.

(6) And if they had believed and feared Allah, then the reward from Allah would have been [far] better, if they only knew.

(7) And establish prayer and give zakah, and whatever good you put forward for yourselves - you will find it with Allah. Indeed, Allah of what you do, is Seeing.

(8) Yes [on the contrary], whoever submits his face in Islam to Allah while being a doer of good will have his reward with his Lord. And no fear will there be concerning them, nor will they grieve.

(9) And who are more unjust than those who prevent the name of Allah from being mentioned in His mosques and strive toward their destruction. It is not for them to enter them except in fear. For them in this world is disgrace, and they will have in the Hereafter a great punishment.

(10) Indeed, We have sent you, [O Muhammad], with the truth as a bringer of good tidings and a warner, and you will not be asked about the companions of Hellfire.
