My point is that Sharia law has no set corpus of law. It is based on the Koran and on the Hadith (sayings and teachings of Mohammed). Certainly, there is no general agreement on the Hadith.
If we cannot agree on what the law is and what needs to be applied to the case under dispute, then the US Court system will be unable to adjudicate the case.
If Disputant A claims that (unwritten) Sharia law says X, and Disputant B claimes that (unwritten) Sharia law says Y and that X is not genuine, and both parties produce scholars supportihg their positions, then the US Court system cannot render a verdict.
Well I suppose they’ll have to appoint a whole lot of experts to help us all out then, won’t they?
That scares me.
