This essay explains the slow but certain adaptation of Islamic law to a general audience:

This article was originally accessible on the public websites of the Chief of Chaplains (http://www.chapnet.army.mil) and the U.S. Army Chaplain Center and School (USACHCS) (http://www.usachcs.army.mil/TACarchive/TAC/tac.htm), but as of 2017 these web sites no longer exist and The Army Chaplaincy no longer appears to be in publication or available online, so I am making a pdf of the article available here.
My very first publication was an encyclopedia article on the early Muslim theologian Abu Ishaq Ibrahim ibn Sayyar al-Nazzam (782–836), whose thought I encountered in writing my dissertation.

My M.A. thesis, completed in 1997 at the University of Colorado in Boulder under the guidance of Fred Denny, Ira Chernus, and Robert Lester, advances a peculiar and, no doubt, very naive idea about how the early Muslim community came to be known as “believers:” in accordance with its pre-Islamic usage, the term initially meant “those who give protection” to the Prophet Muhammad, but came to mean “believers” as the community’s self-definition evolved. This is not an idea I would feel qualified either to defend or refute today, but it has found some sympathetic ears among scholars and may still be of interest.
