Shariah law is a system of Islamic law derived from the teachings of the Quran and the Hadith, which are the sayings and actions of the Prophet Muhammad. It provides guidelines for various aspects of life, including moral conduct, family matters, and social justice. Shariah law is interpreted differently across cultures and communities, leading to variations in its application. While some countries implement it fully, others may incorporate it into their legal systems to varying degrees, often focusing on personal matters like marriage and inheritance.
