Muslim law, derived from the Quran, is a personal and civil law system that governs family matters for Muslims, encompassing various aspects of life. It comprises primary sources such as the Quran and Sunnah, and secondary sources like ijma (consensus) and qiyas (analogical reasoning), with established rules guiding the interpretation of modern and customary laws. The system emphasizes the integration of religious and secular matters and highlights the importance of adhering to divine laws as expressed in the Quran and practiced through the Sunnah.
