Greatness is a phenomenon whereunder specially gifted persons endowed with extraordinary qualities appear on the world stage from time to time. History is the science which studies the phenomenon of greatness. Usually every person who scales the heights of greatness and acquires a place in history is a success from the worldly point of view. There is some peculiarity in the greatness of Ali. He is great, indeed very great, but he was not a success from the worldly point of view in the conventional sense in which the word "success" is understood. We have thus to undertake a study to probe into the causes that militated against the success of Ali from the worldly point of view in spite of his greatness. We will also have to consider how he is great when he did not succeed from the worldly point of view.
