Ravanshenasi & Din

The aim of this research is to identify and explain the methodological foundations of Islamic psychology based on Islamic sources with an emphasis on the thoughts of Allameh Misbah Yazdi. Thus, I referred to the first-hand Islamic sources (the Holy Qur'an and Islamic narrations) as well as Allameh's written works and collected the data related to the process of knowledge, methods of knowledge and tools of knowledge. Then I examined the data and compared them with psychological topics using the method of analyzing the qualitative content of texts. According to the outcomes: 1) the investigation method always depends on the nature of the subject and is not arbitrary. 2) The methods of discovering facts are diverse and the "experimental" method is sufficient for only one group of facts. 3) The "experimental" method is reliable and leads to what is called ‘confidence’ and leads to certainty in some conditions. 4) The "narrative" method is useful for the knowledge of extra-sensory and extra-intellectual realities and is a way to discover reality. 5) The ultimate tool of knowledge that dominates all methods is reason. 6) The selection of methods and techniques are based on values.
