Induction, research, study and contemplation indicate that the true Sharia came to achieve the people’s necessary, needy and ameliorative interests, and that all legal rulings were prescribed to achieve these interests, and that there is no legal ruling except with the intention of achieving one or more of these interests, so that the legislation guarantees all interests in its three divisions. Legislation approach to take care of these interests in two main ways: the legal rulings that secure the creation and formation of these interests, and the legal rulings for preserving, maintaining and nurturing these interests and preventing assault or violation of them, or guaranteeing and compensating for them.
