Explanation of Peace in the Farabi's theory of Medina al-Mussalemah (Peace City) and Kant's permanent peace theory

Different schools and scholars have emphasized the importance of peace and the necessity to realize it as the essential and fundamental necessity in human life. Muslim scholars such as Farabi in the Muslim world and Kant and his followers in contemporary the West, have focused on this issue in their own way. Therefore, the purpose of this study is to study and explain "sustainable peace" in Abu Nasr Farabi and Kant's attitude in a comparative manner. The main question of the research is that: Which of the Kant and Farabi's theories of peace, according to their worldviews, are capable of explaining the nature of peace and realizing it in a stable and steady state?
In a comparative study, the findings of the research show that both theories are considered to be "human" and both put forward a moral attitude towards the realization of peace; but Farabi, with a comprehensive and virtuous look, observes and explains human and society, and the needs of both, such as peace and calmness. In addition, the foundations of peace in al-Farabi's political philosophy, in compared to the Kant's sustained foundations of peace, due to divine-humanity and innateness, as one of the sources of human identity and human security, has the potential to be more feasible and more realistic.
