Shari'a means Law in Arabic, so, the term Shari'a Law becomes an exercise in redundancy.
However, Fiqh is Islamic jurisprudence.
Fiqh is an expansion of the Sharia Islamic law—based directly on the Quran and Sunnah—that complements Sharia with evolving rulings/interpretations of Islamic jurists.
Fiqh deals with the observance of rituals, morals and social legislation in Islam. There are four prominent schools (madh'hab) of fiqh within Sunni practice and two within Shi'a practice. A person trained in fiqh is known as a Faqih (plural Fuqaha).
I hope this clarified the matter.
