which contains a nice definition
"Sharia is more than simply “law� in the prescriptive sense. It is also a methodology through which a jurist engages the religious texts to ascertain divine will. As a jurist-made law, the outcome of this process of ascertaining divine will is called fiqh (positive law), which is the moral and legal anchor of a Muslim’s total existence. Sharia governs every aspect of an observant Muslim’s life."
and an observation
"it is also the set of rules that followers of Islam live by every day .... It’s very controversial in America because, in its governmental sense, it is the exact opposite of standard American ideals."
