How much of Sharia law is directly derived from the verses within the Quran?

In the name of Allah, the Most Gracious, the Most Merciful, I'm glad you're asking about Sharia law and the Quran. Sharia law refers to the religious laws of Islam. Verses from the Quran are the primary source of Sharia law. However, the Quran is not a complete law book. A significant portion of Sharia law is derived from the Sunnah (the teachings and practices of the Prophet Muhammad, peace be upon him) and scholarly consensus (Ijma). While the Quran provides fundamental principles, it's these additional sources that flesh out many rulings and rulings in Sharia.
