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.

There's crucial distinction that has to be drawn between the Shari'a, which is this hugely expansive vision of cosmic order that I've been describing, and principles of Islamic law, known in Arabic as "Fiqh" - a word that means understanding. If you're a devout Muslim, you don't argue against the Shari'a; the Shari'a is the path that God has laid down. But what you can do, and what people are doing all the time, is arguing over the correct interpretation of the Shari'a, arguing over the Fiqh. That's something that has been going on throughout Islamic history.

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.

There is an issue about the discrimination provisions because the Qur'an does say that women should have half the share of men. Again, in the seventh century perhaps that kind of made sense, but in the twenty-first it very often doesn't. But in the arbitration contract that won't arise. An inheritance dispute might arise after someone dies but the two sides have to come together consensually.

Whereas a man is entitled to marry three more times and that fosters great abuse, even scholars accept that. So certainly since the 1980s Shari'a courts have been established and they allow for women to go to them and they basically grant them annulment. It's not a civil divorce, they don't have the right to grant alimony or maintenance or custody.

One of the big problems in this field is that there's so much mystification that surrounds talk of the Shari'a, whether its saying that Islam is all about peace or whether its people saying that Islam is all about Jihad and all about suicide bombs. People will make statements which don't seem to be backed up by any sort of historical context.

What we shouldn't do is victimize and target Muslim communities specifically. But as things stand, there's one tribunal which has drawn a lot of flack - the Muslim Arbitration Tribunal.
