Sharia law...there are several aspects of sharia law..
In plain terms and street talk, it is commonly known as Islamic Law.
However, this does not mean caning for alcohol consumption,cutting of hands for thefts..etc etc..
Sharia law deals with many aspects of day-to-day life, including politics, economics, banking, business, contracts, family, sexuality, hygiene, and social issues.
So plainly put...it is civil and criminal law within the Islamic framework/jurisprundence.
For my non-muslims brothers..there is a Syariah Court in SG and even our Singapore Legal System do have a certain form of Sharia law in the context of AMLA (Administration of Muslim Act) which deal with issues of marriage,wealth, etc etc except for criminal acts whereby its under our local CPC and Penal Code.
No worry,alcohol consumption is not under AMLA.
Indonesia-it is a secular state although it holds the largest Muslim population in the world. It does not conform to sharia laws.
Sharia laws also differ between Sunni camps and Shia camps. Even within Sunni camps there are 4 school of thoughts with different interpretations.
Case in point...consuming of pork is forbidden..a certain school of thought totally banned pork consumption and the use of its by-products, eg: pig's leather, for every day use.
Another school-yes consumption is banned but we may still use its by-products like leather, hair which is used as brushes for artworks for everyday use..
There is no strictly static set of laws of sharia.
Sharia is more of a system of law, a consensus of the unified spirit, based on the Qur'an (the religious text of Islam), hadith (sayings and doings of Muhammad and his companions), Ijma (consensus), Qiyas (reasoning by analogy) and centuries of debate, interpretation and precedent.
