[Joh 16:2b LSB] ... but an hour is coming for everyone who kills you to think that he is offering service to God.
Islamic extremists believe they are offering a service to Allah... not only that, but they're known for beheading the infidel:
[Rev 20:4 LSB] Then I saw thrones, and they sat on them, and judgment was given to them. And I saw the souls of those who had been beheaded because of their witness of Jesus and because of the word of God, and who also had not worshiped the beast or his image, and had not received the mark on their forehead and on their hand. And they came to life and reigned with Christ for a thousand years.
Quran 2:190-193: Fight in the cause of Allah those who fight you, but do not transgress limits; Allah does not love transgressors. [191] And slay them wherever you find them, and drive them out from where they drove you out, for persecution (fitnah) is worse than slaughter. Do not fight them at the Sacred Mosque unless they fight you there; if they do, then slay them. [192] But if they desist, Allah is Oft-Forgiving, Most Merciful.[193] And fight them until there is no more persecution/mischief (fitnah) and religion is for Allah. If they desist, there is no hostility except against the wrongdoers.
No infidels as friends:
Quran 3:28 “Let not the believers Take for friends or helpers Unbelievers rather than believers: if any do that, in nothing will there be help from Allah: except by way of precaution, that ye may Guard yourselves from them. But Allah cautions you (To remember) Himself; for the final goal is to Allah.”
No other religion but Islam is acceptable:
Quran 3:85 “And whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers.”
Maim and Crucify infidels if they criticize Islam:
Quran 5:33 “Indeed, the penalty for those who wage war against Allah and His Messenger and strive upon earth [to cause] corruption is none but that they be killed or crucified or that their hands and feet be cut off from opposite sides or that they be exiled from the land. That is for them a disgrace in this world; and for them in the Hereafter is a great punishment.”
Behead those who believe in Scriptures other than the Quran: Quran 8:12 “[Remember] when your Lord inspired to the angels, ‘I am with you, so strengthen those who have believed. I will cast terror into the hearts of those who disbelieved, so strike [them] upon the necks and strike from them every fingertip.’”
Muster all weapons to terrorize infidels: Quran 8:60 “And prepare against them whatever you are able of power and of steeds of war by which you may terrify the enemy of Allah and your enemy and others besides them whom you do not know [but] whom Allah knows. And whatever you spend in the cause of Allah will be fully repaid to you, and you will not be wronged.”
Unbelievers are stupid: Quran 8:65 “O Prophet! Exhort the believers to fight. If there be of you twenty steadfast they shall overcome two hundred, and if there be of you a hundred (steadfast) they shall overcome a thousand of those who disbelieve, because they (the disbelievers) are a folk without intelligence.”
Kill infidels wherever you find them: Quran 9:5 “Then, when the sacred months have passed, slay the idolaters wherever ye find them, and take them (captive), and besiege them, and prepare for them each ambush. But if they repent and establish worship and pay the poor-due, then leave their way free. Lo! Allah is Forgiving, Merciful.”
Jews and Christians are perverts - fight them: Quran 9:30 “And the Jews say: Ezra is the son of Allah, and the Christians say: The Messiah is the son of Allah. That is their saying with their mouths. They imitate the saying of those who disbelieved of old. Allah (Himself) fighteth against them. How perverse are they!”
Make war on infidels in your neighborhood: Quran 9:123 “O ye who believe! Fight those of the disbelievers who are near to you, and let them find harshness in you, and know that Allah is with those who keep their duty (unto Him).”
Infidels - clothes on fire and boiling fluid: Quran 22:19 “These twain (the believers and the disbelievers) are two opponents who contend concerning their Lord. But as for those who disbelieve, garments of fire will be cut out for them; boiling fluid will be poured down on their heads.”
Do not seek peace with infidels - behead them: Quran 47:4 “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.”
Let the record state: I AM AN INFIDEL!
