Some quotes from the Quran

                                                   Should the unbelievers be killed & who are they?

"O Prophet! Make war against the unbelievers and the hypocrites and be merciless against them. Their home is hell, an evil refuge indeed." (Koran, 9:73)

"When you meet the unbelievers in jihad, chop off their heads. And when you have brought them low, bind your prisoners rigorously. Then set them free or take ransom from them until the war is ended." (Koran, 47:4)

"The punishment of those who wage war against Allah and his messenger and strive after corruption in the land will be to be killed or crucified, or to have their hands and feet chopped off on opposite sides, or to be expelled out of the land. Such will be their humiliation in the world, and in the next world they will face an awful horror." (Koran, 5:33-34)

"When we decide to destroy a population, we send a definite order to them who have the good things in life and yet sin. So that Allah's word is proven true against them, then we destroy them utterly." (Koran, 17:16-17)

"In order that Allah may separate the pure from the impure, put all  the impure ones [all non-Muslims] one on top of another in a heap and cast them into hell. They will have been the ones to have lost. (Koran, 8:37)

"How many were the populations we utterly destroyed because of their sins, setting up in their place other peoples." (Koran, 21:11)

"Remember Allah inspired the angels: I am with you. Give firmness to the believers. I will instill terror into the hearts of the unbelievers: you smite them above their necks and smite all their fingertips off of them." (Koran, 8:12)

 
                                                      Quotes from the Koran

3. "Fight those who do not believe in Allah, nor in the latter day, nor do they prohibit what Allah and His Apostle have prohibited, nor follow the religion of truth, out of those who have been given the Book, until they pay the tax in acknowledgment of superiority and they are in a state of subjection." (9.29)
4. "O you who believe! do not take the Jews and the Christians for friends; they are friends of each other; and whoever amongst you takes them for a friend, then surely he is one of them; surely Allah does not guide the unjust people." (5.51)

(4.89)
9. "The punishment of those who wage war against Allah and His apostle and strive to make mischief in the land is only this, that they should be murdered or crucified or their hands and their feet should be cut off on opposite sides or they should be imprisoned; this shall be as a disgrace for them in this world, and in the hereafter they shall have a grievous chastisement" (5.33)
10. "O Prophet! urge the believers to war; if there are twenty patient ones of you they shall overcome two hundred, and if there are a hundred of you they shall overcome a thousand of those who disbelieve, because they are a people who do not understand." (8.65)
    

                                              Does Jihad [holy war] mean real war? 

 Those who support Muslims try to represent this notion like it looks in the West. They say it is a "struggle" for Muslims' interests. It is not true. This is a bloody war to the final victory until the enemy surrenders to Islam. Traditional Muslim books say that Islam will take over the world but only after Muslims defeat and destroy Jews. These books also say that Jews will hide themselves behind trees and rocks. But the time comes and one "great day" the rocks and trees will start shouting: “Hey, Muslim, there is a Jew behind me! Come and kill him!" Only one tree will keep silence. In Islamic it is called "el oseg" (the tree of Jews). I mean the tree of sne (a bush from which God appeared before Moshe). This tree is mentioned in Muslim books for Muslims not to forget to look for Jews even behind this tree. These books are studied in all Arab schools, and political leaders make quotations from them in their speeches.

                              Les versets en version française

- Ô Prophète, lutte contre les mécréants et les hypocrites, et sois rude avec eux; l'Enfer sera leur refuge, et quelle mauvaise destination! (Sourate 9 :73)
- Lorsque vous rencontrez (au combat) ceux qui ont mécru frappez-en les cous. Puis, quand vous les avez dominés, enchaînez-les solidement. Ensuite, c'est soit la libération gratuite, soit la rançon, jusqu'à ce que la guerre dépose ses fardeaux. Il en est ainsi, car si Allah voulait, Il se vengerait Lui-même contre eux, mais c'est pour vous éprouver les uns par les autres. Et ceux qui seront tués dans le chemin d'Allah, Il ne rendra jamais vaines leurs actions. (Sourate 47 :4)
- La récompense de ceux qui font la guerre contre Allah et Son messager, et qui s'efforcent de semer la corruption sur la terre, c'est qu'ils soient tués, ou crucifiés, ou que soient coupées leur main et leur jambe opposées, ou qu'ils soient expulsés du pays. Ce sera pour eux l'ignominie ici-bas; et dans l'au-delà, il y aura pour eux un énorme châtiment,  excepté ceux qui se sont repentis avant de tomber en votre pouvoir: sachez qu'alors, Allah est Pardonneur et Miséricordieux. (Sourate 5 :33-34)
- Et quand Nous voulons détruire une cité, Nous ordonnons à ses gens opulents [d'obéir à Nos prescriptions], mais (au contraire) ils se livrent à la perversité. Alors la Parole prononcée contre elle se réalise, et Nous la détruisons entièrement. (Sourate 17 :16)
- afin qu'Allah distingue le mauvais du bon, et qu'Il place les mauvais les uns sur les autres, pour en faire un amoncellement qu'Il jettera dans l'Enfer. Ceux-là sont les perdants. Dis à ceux qui ne croient pas que, s'ils cessent, on leur pardonnera ce qui s'est passé. Et s'ils récidivent, (ils seront châtiés); à l'exemple de (leurs) devanciers. Et combattez-les jusqu'à ce qu'il ne subsiste plus d'association, et que la religion soit entièrement à Allah. Puis, s'ils cessent (ils seront pardonnés car) Allah observe bien ce qu'ils oeuvrent. Et s'ils tournent le dos, sachez alors qu'Allah est votre Maître. Quel excellent Maître et quel excellent Protecteur! (Sourate 8 :37-40)
- Et que de cités qui ont commis des injustices, Nous avons brisées; et Nous avons créé d'autres peuples après eux. (Sourate 21 :11)
- Et ton Seigneur révéla aux Anges: ‹Je suis avec vous: affermissez donc les croyants. Je vais jeter l'effroi dans les coeurs des mécréants. Frappez donc au-dessus des cous et frappez-les sur tous les bouts des doigts. (Sourate 8 :12)
