As we have made clear before, there are prime sources for Islamic Thought which directly provide us with the thought and culture we need; such as, the Holy Qur'an and Sunnah, and, they form the base of the Islamic Thought structure. At the present time, if we try to deal with political, economic, moral, philosophical and issues of belief, we will find that there are secondary sources, which are derived from primary ones, as an instance of religious jurisprudence and other juristic studies and researchers that represent a scientific interactive task of religious jurists and researchers in the field of religious jurisprudence and legislation; equally, its principles, which are interacted with rules and primary sources that supply us with the fundamental material of Islamic Thought.

For instance, we can deduce a theory of work and value from much text and analytic juristic studies that deal with work, rent, as well as, ownership. From all verdicts that touch on vital legal rule, we also can derive ideas and concepts with regard to political theory. Thus, all these studies and research, which represent scientific tasks, have taken part in establishing Islamic Thought.

And as the juristic studies are taking a great share in building the high structure of Islamic Thought, in the same manner, philosophical, theological, moral and other studies have taken part in discovering psychology theory and expressing behaviour and history, as well as, philosophy of ethics, politics and, so on. So, if the Islamic researcher and thinker wants to deal with political and economic theory or civilizing matter and the like, he will go back to the Qur'an and Sunnah; equally, fundamentals, rules and analytic studies of religious jurisprudence.

These, produced by researchers and thinkers with regard to philosophy, theology and ethics and to obtain intellectual material along with scientific and methodical restricts to theorize and treat various civilizational cases and problems in a form that saves him commitment and missionary truth; equally, it provides the researcher with endless intellectual wealth.
