Food security is considered to be in line with the objectives of Sharia and a common aspect of various dimensions of national security and even global security. According to international documents, food security depends on four factors: availability of food, access to food, food safety, and sustainability; this is only possible through integrated management and utilizing various capabilities and authorities, and therefore, it has been entrusted to governments. The aim of the present research is to examine the scope of the duties and authorities of the government in maintaining food security from a jurisprudential perspective. Additionally, with reference to the evidence of secondary rulings related to food security, the limits of government authority have been established According to rules such as the prohibition of disruption of the system, the principle of the dignity of the Islamic community, the arguments for the guardianship of the jurist, and the rule of 'no harm', food security is considered a collective duty. However, given the role and functions of the government, its resources, and broad competencies, the responsibility for ensuring food security has fundamentally been placed on the government In order to achieve this important goal, the greatest authorities are established for the Islamic government. Therefore, when necessary, the government has the discretion to even limit the principle of permissibility and the rights of individuals.
