:Umm, I just noticed that Matt links to a book by Tamara Green, which talks about the relationship between Sabianism (or the Harrianian version thereof).  Although that relationship has led some to say that Muhammad placed the Sabian form of paganism as in some way as acceptable as Judaism and Christianity (people of the book), and although there are methods of worship used by Muslims that have roots in different traditions, I don't think Green is making the connection you seem to be making. Best,
