In the third chapter of this book, a scientific review and explanation of the articles of the Constitution of Medina have been given. In addition, legislative and constitutional principles have been taken from the Constitution of Medina, which are superior and higher than the modern constitutional principles in every respect. Also, an attempt has been made to present a comparative analysis of these articles with modern constitutional principles with such a precision of thought that the commonalities and differences between them can be explained. For this comparative analysis, American and British constitutions, the UN Charter and European treaties have been kept in mind as examples, so that their system of governance and the system of governance of the Prophetic era can be highlighted.
