The system of protection of public money in Islam is of particular importance and is not less important than the system of development of public funds and the doors of investment. The Islamic regimes have devoted effective control mechanisms to the past and subsequent public spending. This protects the public money from all forms of excess, deviation, waste and waste. Islamic legislation only to activate the control and make it an integral part of the Islamic financial system, because the Islamic financial system that emerged in the seventh century AD (by consensus of all jurists and specialists), we find the best Islamic systems that emerged in the modern era, The best financial system known to date so far. In terms of financial resources, it is necessary to establish precise and fair controls for the assessment of zakat vessels, for the assessment of taxes, absences and absences, and to establish a constitution for taxes based on equality, ability, appropriateness, certainty and economy in the expenses of collection. The state, the method of recognition and method of assessment, and public spending on the assets of legitimacy, including rationalization of expenditure, and economy, and respect the rules of collection and rules or sections of expenditure, has developed a strict regulatory system to achieve the objectives of Islamic finance. This important and sensitive role played by financial supervision necessitated the establishment of technical administrative bodies whose original and original task is to carry out the previous and subsequent financial control of the financial operations, which necessitated the permanent reflection of its role by giving it broad powers and the provision of material and human resources so that the task entrusted to it is best , And then achieve the first two goals is to protect public money and second-hand spending to serve the national development and the public good. The expansion of the activity of the state and the abundance of its facilities gave financial control special importance, at the level of the relevant texts and the organic aspect of the authorities that exercise this authority and the limits of its independence and effectiveness, the importance of the intervention lies in the recognition of the Islamic view of financial control and the role entrusted to it, and can this system achieve financial goals Because the economic system is homogenous and can not be separated from one another The dynamics of Islamic banks and their success can be achieved only in the appropriate climate, in other words in a comprehensive Islamic economic environment, because the correlation between economic policy and fiscal policy is close. The question is whether the Islamic regime's decision to protect public money is a real guarantee or whether the laws of the situation are more appropriate and effective. If the answer is to confirm the effectiveness of the system established in the Islamic system, the question remains about the reasons why Are pushing us to dispense with them and search for solutions and alternatives in fragile financial and economic systems?
