In this paper the method proposed by Ibn Khaldun in the political and social fields, will be examined in its original dimensions. The political philosophy that started with al-Farabi as a systematic style of thought in Islamic thought used deduction as a mandatory part of the tradition belonging to the philosopher. In one sense, this is a journey from 'description' to 'depiction'. Ibn Khaldun stated that this method remains insufficient in order to explain social phenomena and events, and widening this perspective indicated that political philosophy, in one sense, is compelled to present a utopian social model, and departing from this point criticised al-Farabi as not being a philosophical realist. At this point, the accusations made against the philosophers and his approach to the criticism of al-Siyasah al-Madaniyyah are investigated as to whether or not Ibn Khaldun approached political philosophy from a universal point of view, and if, while making these accusations, the theories of the philosophers were taken into account. Accordingly, Ibn Khaldun's theory of prophethood and happiness and the falasifa's influences on Ibn Khaldun are investigated.
