An Investigation on the historical path of Western models and their effectiveness shows that these models have played an important role in directing the attitude of different countries, especially the Islamic countries; such that the countries which have used the Western models of development have been somehow dependent on the great powers that have invented and supported these models. Due to the impact of Western models of development on Islamic countries, the Islamic-Iranian model of development, posed by Iran's leadership, has lead to paying attention to its foreigner aspects and its application in the world of Islam; this is because such a model cannot be [merely] addressed to the interior due to the transcendental purposes of the Islamic revolution [of Iran]. Therefore I will try to answer the following basic question in this writing: "how can the Islamic-Iranian model of development be posed as an effective model in the world of Islam?" Answering the mentioned question and pointing how the theoretical teachings of the Western models of development impact on Islamic countries, this article will try to explain how the Islamic-Iranian pattern of development will affect the world of Islam.
