UPDATE: Every paragraph makes an interesting point, but I decided to give you one example so you really will go RTWT. From his discussion of the Danish cartoon hullabaloo:
What is the range of jurisdiction of Muslim law? And here you have two opinions. According to the Shi'a and a minority among the Sunnis, Muslim law applies to Muslims wherever they may be in the world. A Muslim who commits an offense against Muslim law, wherever he may be in the world, is subject to Muslim law and must therefore be punished in accordance with Muslim law. The majority Sunni view is that Muslim law only applies in countries under Muslim government. What happens outside is no concern of the Muslim authorities. One distinguished jurist makes his point with an extreme example: A Muslim traveling in the lands of the unbelievers commits robbery and murder. He returns to the lands of Islam with his loot. No action can be taken against him or against his loot because the offense was committed outside the jurisdiction of Islam, and it is therefore up to the juridical and legal authorities of the infidels to take action, if they can and will. Here you have two different opinions relating to an offense committed by a Muslim. That is not the case for the Danish cartoons. This is an offense committed by a non-Muslim. And here the plot thickens. This is discussed by all of the juridical authorities only in the case of a non-Muslim subject of a Muslim state. If a non-Muslim subject of a Muslim state says or does something offensive to the Prophet, he is to be tried —accused, tried, and if necessary, punished. The jurists on the whole tend to take a rather mild view of this offense. They say, well, he is not a Muslim; he doesn't accept Mohammed as the Prophet; we know that. So saying that Mohammed is no prophet does not constitute this offense. It has to be more specifically insulting than that. And, as I say, there is an elaborate juridical literature and case law on this subject.Here's where it gets really interesting:
What is never discussed at all — it is never considered — is an offense committed by a non-Muslim in a non-Muslim country. That, according to the unanimous opinion of all of the doctors of the holy law is no concern of Islamic law, which brings us back to the case of Denmark. Does this mean that Denmark, along with the rest of Europe is now considered part of the Islamic lands, and that the Danes, like the rest, are therefore dhimmis, non-Muslim subjects of the Muslim state? I think this is an interesting question, which can lead to several possible lines of inquiry.
Ok, really now: git.
