Within Islamic liturgy Moslems are adjured to lie to the Infidel. Taqiyya is a law with the Koranic system of total control. In the real world Moslems lie all the time to the Kafir or Unbeliever about Islam, as long as the mendacity aids their cult. Since the Kafir is doomed to Hellfire and must be fought, lying to a non-Moslem is not viewed as immoral, but as a clever implementation of the Allah-thing's will – the only force in the universe with a free-will. All humans are without free-will and must simply obey the diktats of the Allah deity, even if they lie to do so. Moslems must never ever enlist the support of the Kafir unless they are secretly lying to them to further the aims of the Allah-thing:
3:28 Let not the believers take the disbelievers as Auliya (supporters, helpers, etc.) instead of the believers, and whoever does that will never be helped by Allah in any way, except if you indeed fear a danger from them. And Allah warns you against Himself (His Punishment) and to Allah is the final return.
Lying to the Kuffar is okay because the Unbelievers had disobeyed Allah's messenger Muhammad and even planned to kill him [a pity this did not occur]:
8:30 And (remember) when the disbelievers plotted against you (O Muhammad SAW) to imprison you, or to kill you, or to get you out (from your home, i.e. Makkah); they were plotting and Allah too was planning, and Allah is the Best of the planners.
In the spirit of lying and deceit many Moslems are trying to rewrite the meaning of Kafir. The word was originally a pejorative used by Pre-Muhammad Arabs to describe two types of inferiors: 1) a Black slave in Arabia a common enough sight, usually culled from Ethiopia and 2) a peasant farmer outside of the main Arab centers with the same connotations as the word 'pagus' used by the early urbanized Christian elite to describe those who lived in the country. Islam simply took over this pagan Arabian word and used it to describe anyone who did not prostrate themselves to the Allah-deity and who was not a part of the moon cult. By rejecting the cult of Muhammad the 'Kafir' possessed the attributes and characteristics of a slave, or a stubborn stupid farmer. Kafir thus became conflated quickly with Unbeliever, Hypocrites, the unclean, the unjust, the ignorant and the rebellious. These are all words and categories that one finds in the Koran to depict non-Moslems. Today however we have the sorry sight of the Moslems and their Western supporters brazenly redefining Kafir with 'hiding' or 'concealment', or unjustly 'rejecting God'. Allah is the not the same as the Christian God. And the word Kafir has nothing to do with 'hiding' from such a 'thing' as the Allah idol. It means what it means.
Jews and Christians are Kuffar because they are;
“a disbeliever, someone who rejects Allah and who does not believe in Muhammad as the final messenger of Allah." Although Christians and Jews are called the People of the Book (??? ?????? ahl al-kitab), they qualify as disbelievers according to the Koran. The word "kafir" can be offensive to non-Muslims, as it has roots meaning "concealer" and "ingrate" implying that non-Muslims are liars. It is also often used by Muslims as an extremely offensive curse word. Other terms which are used to refer to non-Muslims include "faasiq" (sinner, corrupt) and "munafiq" (hypocrite).”
The Kuffar must be punished, humiliated, killed or know that the Allah thing has doomed them in the afterlife. Kafir and Kuffar are thus sensitive words, and Moslems will do their best to rewrite their meanings. In Moslem apologia both words are now being equated with 'people who reject God'. But Allah is not the J-C God, and Islam has little to nothing in common [other than gross plagiarization which is usually wrong], with the J-C tradition.
Ask yourself this: is a cult which demonizes the Kuffar and advocates his destruction a religion? Or is it what it is, simply a pagan fascist construct to destroy free-will, war against non-cult members, and merge church and state together in a theological totalitarianism which promotes world conquest?
How to become a Kuffar and thereby die in this world or the next and be eternally humiliated:
2:217 Leave Islam.
They question thee (O Muhammad) with regard to warfare in the sacred month. Say: Warfare therein is a great (transgression), but to turn (men) from the way of Allah, and to disbelieve in Him and in the Inviolable Place of Worship, and to expel His people thence, is a greater with Allah; for persecution is worse than killing. And they will not cease from fighting against you till they have made you renegades from your religion, if they can. And whoso becometh a renegade and dieth in his disbelief: such are they whose works have fallen both in the world and the Hereafter. Such are rightful owners of the Fire: they will abide therein.
2:285 Disbelieve in any of the Messengers.
The messenger believeth in that which hath been revealed unto him from his Lord and (so do) believers. Each one believeth in Allah and His angels and His scriptures and His messengers - We make no distinction between any of His messengers - and they say: We hear, and we obey. (Grant us) Thy forgiveness, our Lord. Unto Thee is the journeying.
2:275 Forbid what Allah has made lawful, or make lawful what Allah has forbidden.
Those who swallow usury cannot rise up save as he ariseth whom the devil hath prostrated by (his) touch. That is because they say: Trade is just like usury; whereas Allah permitteth trading and forbiddeth usury. He unto whom an admonition from his Lord cometh, and (he) refraineth (in obedience thereto), he shall keep (the profits of) that which is past, and his affair (henceforth) is with Allah. As for him who returneth (to usury) - Such are rightful owners of the Fire. They will abide therein.
3:28 Give assistance to disbelievers against Muslims.
Let not the believers take disbelievers for their friends in preference to believers. Whoso doeth that hath no connection with Allah unless (it be) that ye but guard yourselves against them, taking (as it were) security. Allah biddeth you beware (only) of Himself. Unto Allah is the journeying.
3:85 Believe in any other religion.
And whoso seeketh as religion other than the Surrender (to Allah) it will not be accepted from him, and he will be a loser in the Hereafter.
5: 44 Don't reject Islamic Law
Lo! We did reveal the Torah, wherein is guidance and a light, by which the prophets who surrendered (unto Allah) judged the Jews, and the rabbis and the priests (judged) by such of Allah's Scripture as they were bidden to observe, and thereunto were they witnesses. So fear not mankind, but fear Me. And barter not My revelations for a little gain. Whoso judgeth not by that which Allah hath revealed: such are disbelievers.
9:65-66 Joke about Islam or anything Islamic.
65. And if thou ask them (O Muhammad) they will say: We did but talk and jest. Say: Was it at Allah and His revelations and His messenger that ye did scoff?
66. Make no excuse. Ye have disbelieved after your (confession of) belief. If We forgive a party of you, a party of you We shall punish because they have been guilty.
39: 45 Dislike Allah.
And when Allah alone is mentioned, the hearts of those who believe not in the Hereafter are repelled, and when those (whom they worship) beside Him are mentioned, behold! they are glad.
98:6 Disbelieve in Muhammad thereby rejecting Islam.
Lo! those who disbelieve, among the People of the Scripture and the idolaters, will abide in fire of hell. They are the worst of created beings.
108:2 Sacrifice to anyone other than Allah.
So pray unto thy Lord, and sacrifice.
Rather irreligious one should say. Moslems can't refute the above. But they will try to rewrite the above.
