Roots of the law

Quran

The Quran, understood by Muslims to be the word of God, is the first root of the law. The Quran teaches first and foremost monotheism, the Day of Judgment, the need to develop God-consciousness, to act with justice, and the responsibility to abide by the word of God. In addition, the Quran teaches ethics, and provides detailed information on inheritance and other issues.  The Quran contains a few legal rulings, forbidding killing, adultery, theft and slanderous accusation.
