The sophisticated issues on theism, due to God's glory, have made the Muslim philosophers confess the weakness of intellect and rationality. These scholars, particularly from the time of Mollasadra untill now, are greatly indebted to Imam Ali for his exalted words and sayings in Nahj-al-Balaghe concerning theism. Among the theistical issues enlightened in Nahj-al-Balaghe are: the levels of pure monotheism, the possibility of knowing God, the levels of the human's knowledge of God, the manner of scribing God to perfection attributes, God's way of talking, God's fate and destiny, etc.
It seems that the divine and intellectual sages' efforts together with taking advantage of Imam Ali's ideas and beliefs within the framework of hermeneutics have led to many logically plausible findings. These findings have been in line with the Qur'nic verses and the Islamic mystics' views.
