Shah Wali Ullah has observed: "Chivalry and strength of character, humanity and sincerity which are attributes of great men were represented in abundance by Ali. He is the father of Islamic learning, and his intellectual attainments were due to the ideal training of The Holy Prophet. He was a Hafiz, and a great authority on the Quran. He was the greatest Mujahid and jurist of his time, and one of the greatest of all times. He was one of the greatest orators of early Islam."
