From the viewpoint of Allameh Tabataba’i, unity is an instinctive phenomenon and this issue has been emphasized in various Quranic verses and narrations. He has argued that the viewpoint of the Quran about unity is God’s non-numerical unity and he has supported his idea by various citations from the Quranic verses and narrations. Referring to the verse that rejects having knowledge domination over God, he considers the Divine essence loftier than any expression. He further explains the verses in which God has been described as unmerciful unity and the verses in which He has been described as free from any attribute but the description of His sincere servants on the basis of boundlessness of the Divine essence and, accordingly, interprets the narrations in which God has been described as outwardness and inwardness
