Sharia law, or simply Islamic law, is part of Islamic traditions and is based on such religious perspectives of Islam as hadith and the Koran. This law defines all aspects of the life of a person who decides to follow the Islamic religion, and finance and banking are no exception. Banks and other financial institutions operating under Islamic law are generally considered to comply with Sharia law. While all Islamic banks operate in accordance with Sharia law, more and more Western banks are also making sure to comply with Sharia law and thus open up a new customer base and partners. http://www.confiduss.com/en/info/blog/article/sharia-law-banks/
