Sharia is not divine, but its intent was to serve justice. Anything that is divine cannot be flawed and unjust. Sharia has many components in it that are downright wrong.
Sharia is indeed a body of regulations that punishes the violators (per the interpretation of the writers), beheading, stoning, unjust divorce, apostasy, blasphemy all originate from those books.
God willing, I will write a rebuttal to a few points that are an error on the part of the author of this article.
