Say "Peace"

[6:54] And when those who believe in Our communications come to you, say: Peace be on you, your Lord has ordained mercy on Himself, (so) that if any one of you does evil in ignorance, then turns after that and acts aright, then He is Forgiving, Merciful.

[25:63] And the servants of the Beneficent God are they who walk on the earth in humbleness, and when the ignorant address them, they say: Peace.

[27:59] Say: Praise be to Allah and peace on His servants whom He has chosen: is Allah better, or what they associate (with Him)?

[28:55] And when they hear idle talk they turn aside from it and say: We shall have our deeds and you shall have your deeds; peace be on you, we do not desire the ignorant.

Misjudging others is unIslamic

4:94        O ye who believe! When ye go abroad in the cause of God, investigate carefully, and say not to any one who offers you a salutation: "Thou art none of a believer!" Coveting the perishable goods of this life: with God are profits and spoils abundant. Even thus were ye yourselves before, till God conferred on you His favours: Therefore carefully investigate. For God is well aware of all that ye do.

22:17 Those who believe (in the Qur'an), those who follow the Jewish (scriptures), and the Sabians, Christians, Magians, and Polytheists,- God will judge between them on the Day of Judgment: for God is witness of all things.

And…

5:69 Those who believe (in the Qur'an), those who follow the Jewish (scriptures), and the Sabians and the Christians,- any who believe in God and the Last Day, and work righteousness,- on them shall be no fear, nor shall they grieve.

Jehad the Strive

4:95        Not equal are those believers who sit (at home) and receive no hurt, and those who strive in the cause of God with their goods and their persons. God hath granted a grade higher to those who strive with their property and persons than to those who sit (at home). Unto all (in Faith) Hath God promised good: But those who strive fight Hath He distinguished above those who sit (at home) by a special reward,-

4:96        Ranks specially bestowed by Him, and Forgiveness and Mercy. For God is Oft-forgiving, Most Merciful.

Jehaad : Understanding The word جهاد and its Purpose in Quran

61:10		O you who believe! shall I lead you to a merchandise which may deliver you from a painful chastisement?
61:11		You shall believe in Allah and His Apostle, and struggle hard in Allah's way with your property and your lives; that is better for you, did you but know!
61:12		He will forgive you your faults and cause you to enter into gardens, beneath which rivers flow, and goodly dwellings in gardens of perpetuity; that is the mighty achievement;
4:95	The holders back from among the believers, not having any injury, and those who strive hard in Allah's way with their property and their persons are not equal; Allah has made the strivers with their property and their persons to excel the holders back a (high) degree, and to each (class) Allah has promised good; and Allah shall grant to the strivers above the holders back a mighty reward:

9:24

Say: If your fathers and your sons and your brethren and your mates and your kinsfolk and property which you have acquired, and the slackness of trade which you fear and dwellings which you like, are dearer to you than Allah and His Apostle and striving in His way, then wait till Allah brings about His command: and Allah does not guide the transgressing people.

9:81	Those who were left behind were glad on account of their sitting behind Allah's Apostle and they were averse from striving in Allah's way with their property and their persons, and said: Do not go forth in the heat. Say: The fire of hell is much severe in heat. Would that they understood (it).
9:82	Therefore they shall laugh little and weep much as a recompense for what they earned.
9:83	Therefore if Allah brings you back to a party of them and then they ask your permission to go forth, say: By no means shall you ever go forth with me and by no means shall you fight an enemy with me; surely you chose to sit the first time, therefore sit (now) with those who remain behind.
9:84	And never offer prayer for any one of them who dies and do not stand by his grave; surely they disbelieve in Allah and His Apostle and they shall die in transgression.
9:85	And let not their property and their children excite your admiration; Allah only wishes to chastise them with these in this world and (that) their souls may depart while they are unbelievers
9:86	And whenever a chapter is revealed, saying: Believe in Allah and strive hard along with His Apostle, those having ampleness of means ask permission of you and say: Leave us (behind), that we may be with those who sit.
9:87	They preferred to be with those who remained behind, and a seal is set on their hearts so they do not understand.
9:88	But the Apostle and those who believe with him strive hard with their property and their persons; and these it is who shall have the good things and these it is who shall be successful.
9:89	Allah has prepared for them gardens beneath which rivers flow, to abide in them; that is the great achievement.

Qitaal :The Fight of weapons in war 
Understanding the word  قتال  and its purpose in Quran

22:39 Permission (to fight) is given to those upon whom war is made because they are oppressed, and most surely Allah is well able to assist them;

4:74	Therefore let those fight in the way of Allah, who sell this world's life for the hereafter; and whoever fights in the way of Allah, then be he slain or be he victorious, We shall grant him a mighty reward.
4:75	And what reason have you that you should not fight in the way of Allah and of the weak among the men and the women and the children, (of) those who say: Our Lord! cause us to go forth from this town, whose people are oppressors, and give us from Thee a guardian and give us from Thee a helper.
4:76	Those who believe fight in the way of Allah, and those who disbelieve fight in the way of the Shaitan. Fight therefore against the friends of the Shaitan; surely the strategy of the Shaitan is weak.
4:77	Have you not seen those to whom it was said: Withhold your hands, and keep up prayer and pay the poor-rate; but when fighting is prescribed for them, lo! a party of them fear men as they ought to have feared Allah, or (even) with a greater fear, and say: Our Lord! why hast Thou ordained fighting for us? Wherefore didst Thou not grant us a delay to a near end? Say: The provision of this world is short, and the hereafter is better for him who guards (against evil); and you shall not be wronged the husk of a date stone.
4:78	Wherever you are, death will overtake you, though you are in lofty towers, and if a benefit comes to them, they say: This is from Allah; and if a misfortune befalls them, they say: This is from you. Say: All is from Allah, but what is the matter with these people that they do not make approach to understanding what is told (them)?
4:79	Whatever benefit comes to you (O man!), it is from Allah, and whatever misfortune befalls you, it is from yourself, and We have sent you (O Prophet!), to mankind as an apostle; and Allah is sufficient as a witness.
4:80	Whoever obeys the Apostle, he indeed obeys Allah, and whoever turns back, so We have not sent you as a keeper over them.
3:167		And that He might know the hypocrites; and it was said to them: Come, fight in Allah's way, or defend yourselves. They said: If we knew fighting, we would certainly have followed you. They were on that day much nearer to unbelief than to belief. They say with their mouths what is not in their hearts, and Allah best knows what they conceal.
3:168		Those who said of their brethren whilst they (themselves) held back: Had they obeyed us, they would not have been killed. Say: Then avert death from yourselves if you speak the truth.
3:169		And reckon not those who are killed in Allah's way as dead; nay, they are alive (and) are provided sustenance from their Lord;
3:170		Rejoicing in what Allah has given them out of His grace and they rejoice for the sake of those who, (being left) behind them, have not yet joined them, that they shall have no fear, nor shall they grieve.

5:44	Surely We revealed the Taurat in which was guidance and light; with it the prophets who submitted themselves (to Allah) judged (matters) for those who were Jews, and the masters of Divine knowledge and the doctors, because they were required to guard (part) of the Book of Allah, and they were witnesses thereof; therefore fear not the people and fear Me, and do not take a small price for My communications; and whoever did not judge by what Allah revealed, those are they that are the unbelievers.
5:45	And We prescribed to them in it that life is for life, and eye for eye, and nose for nose, and ear for ear, and tooth for tooth, and (that there is) reprisal in wounds; but he who foregoes it, it shall be an expiation for him; and whoever did not judge by what Allah revealed, those are they that are the unjust.
2:246		Have you not considered the chiefs of the children of Israel after Musa, when they said to a prophet of theirs: Raise up for us a king, (that) we may fight in the way of Allah. He said: May it not be that you would not fight if fighting is ordained for you? They said: And what reason have we that we should not fight in the way of Allah, and we have indeed been compelled to abandon our homes and our children. But when fighting was ordained for them, they turned back, except a few of them, and Allah knows the unjust.

Islam means Peace

5:16] With it, GOD guides those who seek His approval. He guides them to the paths of peace, leads them out of darkness into the light by His leave, and guides them in a straight path.

[10:25] GOD invites to the abode of peace, and guides whoever wills (to be guided) in a straight path.
