“Sharia” applies to all field of life. “Sharia”-compliant corporations merely means corporation that do not violate Islamic *BUSINESS* law, e.g., not loaning money with interest, etc. Apart from the name, this has nothing to do with beheading women.

In the Talmud (the main source of Jewish religious law), formulated from ca. 200 BC to 500 AD, some laws deal with slavery, whose legality is (unsurprisingly) taken for granted. Other laws deal with dietary restrictions: what food is kosher. Does this mean that if I buy kosher food I am supporting slavery? Of course not.
