Political geography is one of the branches of geography. The science of political geography is known as the first degree knowledge and the philosophy of political geography is known as second degree knowledge. The philosophy of political geography has been examined and explained from the philosophical point of view of different schools, but all the mentioned schools have acted incompletely in explaining it. In this research, the philosophy of political geography from the approach of Islam has been explained in three areas of ontology, epistemology and methodology. In the ontology of the subject, the definition, area and territory, essence and nature and legality have been discussed. In epistemology, tools include senses and experience, logical and intellectual reasoning, attention and cultivation, testimony and revelation and Sources including nature, intellect, heart and history have been discussed in the field of religious knowledge. Therefore, it is assumed, Islam has a defensible theoretical basis in all political and social fields, and such a research has been done due to eliminate the gap in the field of philosophy of political geography from the perspective of Islamic thought. Accordingly, the necessary formulation with the reasoned content of Islamic political geography has been compiled, referring to Islamic texts and sources, including the Holy Quran, narrative sources, texts of political and historical jurisprudence, as well as the works of Muslim thinkers in this regard. The present study is conducted in a descriptive-analytical method, especially content analysis, and the results show that Islamic thought in the field of social sciences, and especially in the field of political geography, is based on an approach called the approach of revelatory rationality.
