Even in inquiries from his is stated that this is not a simple recommendation, however,is not a religious Fatwa. However, it is incompatible with the teachings of classical economics and individual freedom of choice and on the other hand in the history of Islam, the religious Fatwa except by some constitutional scholars is not seen in this case. According to the above a question that comes in mind is what is the basis of all this emphasis and its purpose?Is it possible to trace those in Islamic sources or merely a recommendation based on the specific conditions of country? which implications do the biographies of Constitutional scholars in this field have?The research method is a descriptive analytic and based on historic grounded theory method, in which search among written documents from Supreme Leader and historical documents and events related to constitution.
Analysis of more than 20historical texts and documents important and relevant of Constitutional scholars and of Supreme Leader's during his leadership on this shows that the idea of boycotting the foreign products and on the flip side of it promoting and strengthening use of national products is based on the 4: nationality,rejection of way,prohibiting imitation of infidels and strengthening the national economy.
