Shariah is Islamic law derived from the teachings of the Quran and of Muhammad. It is not a list of rules but rather a set of principles on aspects of life, including marriage, divorce, finance and rituals such as fasting and prayer.
Islamic scholars interpret Shariah in different ways, and Muslims around the world vary in their practice of it.
Aspects of Shariah are included in the legal codes of Muslim countries, including Saudi Arabia, Kuwait, the United Arab Emirates, Pakistan and Iran. In the West, there is a long-running debate as to whether Shariah can coexist with secularism and democracy.
