Koranic interpretation is based on the idea of abrogation, the earlier peaceful verses, which are in the Koran, are abrogated or replaced by the warlike and hateful texts.
The later verses of the Koran abrogate or replace earlier texts. Here is the last verse written about the People of the Book (Jews/Christians). This is the final word. It calls for Muslims to make war on the People of the Book who do not believe in the religion of truth, Islam.
9:29 "Make war on those who have received the Scriptures [Jews and Christians] but do not believe in Allah or in the Last Day. They do not forbid what Allah and His Messenger have forbidden. The Christians and Jews do not follow the religion of truth until they submit and pay the poll tax [jizya] and they are humiliated."
The last sentence "They do not forbid . . . " means that they do not accept Sharia law: "until they submit" means to submit to Sharia law. Christians and Jews who do not accept Mohammed as the final prophet are Kafirs" (literally concealers: those who disregard the truth of Islam).
A Muslim is not the friend of the Kafir (concealer)
3:28 "Believers should not take Kafirs as friends in preference to other believers. Those who do this will have none of Allah's protection and will only have themselves as guards. Allah warns you to fear Him for all will return to Him."
Likewise, a Kafir can be mocked (83:34), beheaded (47:4), plotted against (86:15), terrorized (8:12), evil (23:97), disgraced (37:18), and cursed (33:60).
There are two sets of rules: a Muslim is a brother to another Muslim. Whereas something that is not true is not always a lie.
[Bukhari 3,78,618] Mohammed: "A man who bring peace to the people by making up good words or by saying nice things, though untrue, does not lie."
