The late founder of the Islamic Republic once through one of historic message in this regard said as following:
“What can I say about the personality of Imam `Ali? Who else may justly say anything about him? The multifarious dimensions of this great personality are beyond human assessment. Just like the names of God, the Exalted, the dimensions of a perfect man, who is the manifestation of all divine names and attributes, are beyond calculation. We cannot describe even a single attribute of Imam Ali.
(Sahifeh-ye Imam, vol. 20, p. 106)
