Known as the Third Teacher, Abu Ali Moskwiyyah is among the philosophers who cooperated with Ale Buiyye political system, in 4th and 5th century (AH). Civil wars and political crises made him put politics aside and enter into the field of political thought to find solutions for the problems of the time. In this way, he formed a system of ideas in which sharia was , in fact , the reconstruction of an ideal system from which the Islamic society had moved away. Moskwiyyah suggested the "ethical purification" of the society to remove the existing moral deviations. To benefit from everlasting teachings, he recommonded seeking for "political experience" in "history". He , also, included "Philosophy" in his system of ideas, but what has an essential role in this system is "politics". That is why we come across with terms such as: "the political sharia", "civil ethics", "political history", and "political philosophy in his fromework of ideas . So, considering Moskwiyyah as a "political philosopher" seems inevitable.
