I realized that the ignorance was profound. I don't mean that in a pejorative sense, it's just that people didn't know what the Shari'a was, as such. They knew that it was something good. I should say perhaps that the Shari'a, etymologically in Arabic, means a desert path to water. It means a path towards salvation, in the seventh-century context, to the desert people. If you have a path to water, that's the path you want to take to get you where you want to get to; where you should get to. And that much was clear but beyond that people didn't know what the rules were.

The Shari'a itself - this is possibly a kind of verbal debate - is understood to be something different from the Fiqh, and the Fiqh is the man-made element and the Shari'a is theoretically the divine element but it depends on one's personal beliefs.

There have been lots and lots of fatwas against violence. But it is an interesting question. A Mufti is the person that issues the fatwa and you'll find Muftis at all the Madrasas. Basically once you've studied for long enough you have the authority to issue a fatwa. But there are limits. I can bang on and on on the point but all I'm really saying is that there isn't a simple answer.

I didn't quite know whether I was writing for the non-Muslim or the Muslim, and at the end of the day I'm writing, I hope, for people who are interested, whatever their faith. Even if they don't have any faith. As a barrister I had certain advantages - I could think like a lawyer and I knew how all the laws were fitted together and all the rest of it. One of the things I realized pretty early on while I was writing book about Shari'a was that that was as much a hinderance as it was a help because the Shari'a isn't just a system of rules.

The one fatwa that everyone here is probably familiar with is the Salman Rushdie fatwa, but a fatwa doesn't have to be a violent thing at all. A fatwa is simply a ruling on Islamic law; there can be fatwas on clothing.

Ayatollah Khomeini issued a fatwa to that effect, which was then given effect in the Islamic Republic of Iran, so in the Islamic Republic of Iran, it's flexible enough to allow for sex changes, and it encourages sex changes. But if you want to change your religion in Iran, you've got some serious problems. There are other problems. You're allowed to change sex, but if you want to be a homosexual, theoretically at least, you face the death penalty. Quite how often these penalties are carried out is a moot point, but it's there on the statute books.

The Muslim Arbitration Tribunal, if you look at its website, it basically deals with commercial disputes, it's not allowed to deal with matters involving children, it's not allowed to deal with criminal matters, it's subject to judicial review, it's subject to the Human Rights Act, it's subject to the Children's Act, and it's completely proper and right that it should be subject to all those things.
