The early Islamic wars, including pivotal battles such as Badr, Uhud, and Yarmouk, were not only defining moments in the history of Islam but also featured complex military strategies that shaped the trajectory of the Islamic Empire. This paper applies mathematical modeling techniques to analyze the strategic decisions and outcomes of these key conflicts. By employing game theory, optimization models, and decision analysis, the study explores how the commanders of early Islamic military campaigns optimized resource allocation, troop movements, and battle tactics. Mathematical models provide a new perspective on the decision-making processes and strategic planning involved in these wars, highlighting the roles of risk, uncertainty, and adaptation in military strategy. Through the analysis of historical data and comparison with modern military strategy models, the study demonstrates how mathematical tools can offer insights into the successes and challenges faced by early Islamic armies. The findings suggest that while early Islamic commanders had limited technological resources, they effectively used available intelligence and psychological strategies, which can be understood through mathematical analysis.
