And the symbology of Abraham's story of sacrifice is narrative of Sufi principle. The Sufis of the ancient school, which now exists in different parts of Asia, trace their origin from the time of Abraham, which makes a link of the Sufi school with the ancient school of Egypt. The story is that God asked Abraham, to test his devotion, that he must bring his son a sacrifice to God. And he obeyed, and he brought his son to the altar. And then they saw that instead of his son there was a sheep, and the son was standing on one side. Abraham thanked God for His great mercy, and at the same time passed through that test.
