There were periods in Islamic history when things like apostasy and blasphemy were made punishable. So you know it kind of depends - there's no argument, quite apart from the question of the divine or otherwise nature of the Qur'an, that huge swathes of Islamic law are man-made. Clerics here - in maintaining their power, will often try to elide that and say "Well no, actually this isn't man-made at all. Stoning is part of the divine revelation." It isn't in the Qur'an but the way this has been done over the years is to take the Hadith.

I work in the human rights field and there are serious conflicts between certain interpretations of Islamic law and human rights. That's something which I don't make any bones about at all, it's something which I think is very important for everyone to address, including the Muslim community, and many Muslims are addressing that issue.

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.

The politicized version of Shia Islam that we see in the Islamic Republic post-1979 clearly is very conservative, but, there are other things one could say about Ayatollah Khomeini's concept of a Shia state because that in itself is a blasphemy as far as most Shia clerics are concerned. There's a theory that he developed in the early 1960s in the town of Najaf talking about - well not liberalism, necessarily, but flexibility though.

People are coupling and decoupling all the time in Great Britain. The fact that Muslims choose to precede it with a certain formula of words, shouldn't bar them from anything. But, no one's saying that polygamy should be institutionalized in this country. That Muslim's uniquely should be allowed to have two or three or four marriages.

The first rules about Islamic law weren't even written down for a century and a half after the Prophet's death, and it was another five centuries, half a millennium, before they assumed anything like a definitive form. So there have always been huge arguments over what Islamic law actually requires. There are four main schools of law in Sunni thought and there's a separate school of law in Shia thought, so these arguments do take place.
