A Reflection of Avicenna and Khwajeh Nasir al-Din Tusi on the Detailed Knowledge of God

The main question of the present article is: What are the commonalities and differences between Ibn Sinachr('39')s and Khawaja Nasirchr('39')s approach to Godchr('39')s detailed knowledge? And to what extent have these two sages been able to answer the problem? According to the findings of the study, Sheikh al-Rachr('39')is, based on the principle of causality and formality, proves and explains the knowledge of God in detail, but Khwajeh Tusi presents other theories by presenting objections to Ibn Sinachr('39')s words about Godchr('39')s knowledge of small and changing beings; According to Khwajeh, Godchr('39')s knowledge of abstractions is attributed to specific external beings and to matter, in their forms in the intellect. One of the most important results of the present study, which was performed by descriptive-analytical method, is that: The presentation of these theories, despite the fact that it was incapable of proving the detailed knowledge that is the essence of God; But it paved the way for the acquisition of later philosophers such as Sheikh Ishraq in explaining the knowledge of God as action.
