Concept exploration uses library sources that are analyzed to obtain the basis for conceptual differences and explore the relationship between illat, hikma and sabab. The correlation between Illat, Wisdom and Sabab can be divided into two: first; the relationship between illat and sabab to wisdom, wisdom is complementary to both in providing a more philosophical construction of law, not just punishing. Second; The relationship between illat and sabab is complementary if you look at the generality and specificity of the two.
