Jihad, then and now
This leads to the fourth question: what is the relevance of all this to the modern world? The Muslims have not practised missionary jihad since the decline of the Ottoman empire, at least not under the sponsorship of states, and to my knowledge there are no serious calls for its return. What the tradition has left is a strong activist streak, a sense that it is right to fight for your convictions. "Look at you, you Christians, with your passivity you have turned religion into something that doesn't exist", as demonstrators against Salman Rushdie said in Paris in March 1989. But to understand the fundamentalists we need to go to the other kind of jihad, the one practised when the Muslims are politically weak.
What happens when Muslim territory falls under infidel sovereignty? Can Muslims stay on and live under non-Muslim rule? Some jurists said yes, others denied it on the grounds that Islamic law could only be applied in full under Muslim sovereignty. If infidels conquered Muslim land, the Muslims had to emigrate, they had to make a hijra to a place where they could practice Islamic law - either an existing Muslim state or a new one set up by themselves - and then they should start holy war in order to reconquer their homeland. Not all scholars subscribed to this view, but it was upheld by many in response to the loss of Muslim territory in Spain and it also inspired anti-colonial movements in British India, French Algeria and elsewhere.
Imagine an even worse scenario: what happens when not a single Islamic state exists any more, when all political power has turned infidel? The answer is the same with greater urgency (and probably less disagreement too). You must emigrate to a place where you can establish a Muslim state and then you must wage holy war to get it going. In both cases, the model is Mohammed: first he lived in pagan Mecca, under infidel sovereignty, then he emigrated to Medina where he established a Muslim polity and started jihad and conquered Mecca, which he cleansed and purified; thereafter his followers began the conquest of the rest of the world, in what eventually turned into missionary warfare.
Jihad for the recovery or actual creation of Muslim sovereignty (as opposed to its expansion): that's the type that is practised today. Modern fundamentalists (or Islamists) call it defensive jihad, though it is not what the classical Muslims understood by that term. It makes sense to them, partly because they feel on the defensive; partly because everyone recognises the legitimacy of defensive war; and not least, because participation in defensive jihad is an individual obligation, like fasting and prayer, not a communal duty like the missionary type, which you don't have to undertake as long as others are doing it. So calling your jihad defensive is good for mobilisation.
Whatever you call it, the missionary element is greatly reduced in this type of warfare. Of course, you have to convert people to your own beliefs in order to get them together for state formation and conquest, but the emphasis is not so much on saving people as on saving Islam, especially in the more extreme version when no Islamic state is deemed to exist at all. For Islam can't exist without political embodiment, according to this view. There has to be a place on earth where God rules. Without it, collective (and individual?) life ceases to have any moral foundations.
In the past, jihad for the actual creation of Muslim sovereignty was only practised by heretics, for it was only heretics who would deny that existing states were Islamic. The very first to do so were the Kharijites, who are almost as old as Islam itself. There were also Shi'ites who did. But the Sunnis always accepted their own states as Islamic in some (sometimes minimalist) sense, at least until the 18th century, and most still do, including the Muslim Brotherhood, and Hamas. Their jihad is concentrated on the recovery of Muslim territory, such as Palestine, and the defence of Muslims in places such as Chechnya. They don't attack infidels elsewhere, nor don't they believe in fighting Muslim rulers, or not any more.
But other fundamentalists deem all Muslim states, or even all Muslim people apart from themselves, to be infidels. Al-Qaida is among them. They direct their efforts against America rather than fellow Muslims because America is deemed to be behind everything wrong in the Muslim world - you can't correct the shadow cast by a crooked stick, as Osama bin Laden is said to have put it. But when America, the crooked stick, has been removed, it will be the turn of the Muslim world in general, and by that they mean all countries with a Muslim population, which is in effect the whole earth by now. So as far as al-Qaida is concerned, the old distinction between the abode of Islam and the abode of war has disappeared.
The extreme fundamentalists can't see any difference between living in Egypt, for example, and living under non-Muslim rule, thanks to the all-pervasive influence of the modern state. In the old days the political domain was also worldly and corrupt, but the social domain was still shaped by Islam. Nowadays, however, it is the state that regulates marriage, divorce, inheritance, trade, finance, work, health, childcare, schooling, higher education, and so on, often with attention to what the sharia says, but freely reshaping it to fit modern, secular aims which originate in the infidel and politically dominant west.
So one way or the other, Muslims are ruled by the west wherever they live, not just politically but also socially and culturally. Wherever they are look, they are being invaded by so-called western values - in the form of giant billboards advertising self-indulgence, semi-pornographic films, liquor, pop music, fat tourists in indecent clothes and funny hats, and politicians lecturing people about the virtues of democracy. Religion does not actually shape the social realm any more, except rhetorically. All that religion shapes in modern Muslim societies is voluntary associations such as Sufi orders, Muslim brotherhoods, and fundamentalist cells, which fall short of being whole societies, let alone states, and which you can set up in non-Muslim countries too. So in effect, as the fundamentalists see it, all Muslims have become diaspora Muslims.
Some Muslims are happy with this. They want the socio-political order to be secularised; they want religious affiliation to be voluntary. They are the secularists, the people we have no trouble understanding. But to the fundamentalists, or rather to the extremists among them, all Muslims are now living in a new age of ignorance (jahiliyya) such as that which prevailed in pagan Arabia before the rise of Islam. This is why one must get together to reenact Mohammed's career and save Islam.
Establishment religious scholars often compare such fundamentalists to the Kharijites of the early Islamic period, and with good reason. They are amazingly similar. There is the same declaration of other Muslims to be infidels, the same sense of fighting for God rather than for people - God has to rule even if the whole world is going to perish in the attempt -the same utter ruthlessness too. The Kharijites allowed assassinations, indiscriminate slaughter, the killing of men, women and children alike, much like Abu Musab al-Zarqawi. Their missions were often suicidal, too, not in the sense that they'd set out on individual missions bound to result in death, but rather in the sense that tiny numbers would take on huge forces bound to exterminate them, inspired by a quest for martyrdom. They had sold their souls to God, as they put it, and got a good price for them, too, namely Paradise; they went into battle intending to collect the price. And then as today, women would fight along with the men.
There is of course no direct link whatever between the Kharijites and modern fundamentalists. People like Osama bin Laden and Ayman al-Zawahiri don't even seem to know their own tradition all that well. Rather, they have stripped Islam of practically everything that most Muslims consider to be their religion.
What's left is an archetypal monotheist of the confrontational type: a separatist and militant zealot. In the view of such zealots, God's people can't live together with infidels, they must have their own political space. Right and wrong must be embodied in separate communities, and every Muslim must fight to bring this about.
The history of Islam starts with a great separation of God's people from the rest of mankind by force of arms, and Islamic history thereafter is punctuated by regular attempts to restore the separation, to get rid of all the complexity that obscured the simplicity of the original vision. Those who engaged in such attempts tended to come from the more peripheral areas of the middle east, often from a tribal background, and they were always minorities. The fundamentalists, too, are only a small minority today. But you don't need an awful lot of people of this kind for an awful lot of trouble.
