When we use those principles, in a case, (i.e., the logic rule and sound thinking) for scientific research and in every science or any other field of thinking, it means that the researches are being performed due to correct bases and provide fruitful results. It, also, becomes apparent that every science or knowledge has its own, suitable research, which may be used by the scientists and researchers to deal with a certain subject.

So, the research methods that touch on the material sciences, such as: medicine, physics and chemistry is quite different from the one concerning history, sociology, philosophy, belief, etc.

When we prepare to do research into Islamic thought; i.e., the creed, jurisprudence principles, interpretation, policy, economy, sociology, ethics, history and narration; we should first consider the specification of the scientific basis for the research methods to reach a strict, scientific conclusion and that it be sound with regard to the Islamic characteristic.

In other words, we should establish, in our mind, that we are going to fulfill two criteria in performing research, theories and Islamic studies as follows: With Scientism and Realism With Islamic Originality and Commitment After this introduction, we will become quite sure, that there are general, scientific principles that combine with all other research and study or scientific theory, whether they are material ones; like physics, medicine, astronomy and chemistry or human ones; such as, economy, ethics, philosophy, creed, sociology, jurisprudence, law, history, etc., in so much as all those sciences have worked, reciprocally, due to key axioms and principles.

For instance, the agreement with the causality law and with non-contradiction, as well as, setting aside any case until it can be proved correctly by evidence, etc. Therefore, all the sciences and knowledge would start from those axioms and bases; just like the physical research and belief in a supreme creator, as well as, the other historical, jurisprudential, geometrical, medical studies, etc.

The mentioned fact was approved by many scientists and researchers of natural sciences; as well as, those in the human and divine sciences. Let us put forward some of those views, thus: As a fact, for the studied sciences, man has used the mechanism idea and it is identified as one of his instruments and means.
