The way to the desired knowledge is marked by the perfection and beauty of the Sharia, founded on wisdom, righteousness, and guidance. Understanding the comprehensive principles of both foundational and subsidiary rulings is among the most crucial sciences, offering immense benefits. These principles serve as the foundation for construction and the roots of trees. Through rules and principles, knowledge is established, strengthened, and developed. This is why Imam Al-Sa'di focused on this field for the significant benefits it provides to learners.
