This research presents a comparative study on the duties of the ambassador from two perspectives: Islamic jurisprudence and international law, in light of the historical and diplomatic developments that have influenced the role of ambassadors. The researcher aimed to highlight the importance of the ambassador in establishing relations between nations, clarify the legitimacy of the ambassador’s role and his qualifications, and identify the differences between his functions in the past and present.
The study employed both inductive and analytical methodologies to compare Islamic legal texts with international legal provisions. The findings reveal that Islam endorsed the role of the ambassador and endowed it with a moral and missionary dimension, whereas modern international law regulates it within specific diplomatic frameworks, especially following the Vienna Convention. The research outlines the ambassador’s responsibilities toward both his home country and the host country, emphasizing the importance of adhering to international laws and respecting national sovereignty.
The study concludes that, in Islam, the ambassador is not merely a messenger but a representative of religion and values. International law, on the other hand, affirms his role in promoting international peace. Furthermore, the nature of modern international relations has led to the emergence of the concept of "permanent diplomatic representation" through embassies.
