He Who Knows His Soul

The Prophets all make each other known. Jesus says, "O Jew, you did not know Moses well. Come and see me so that you may know Moses." Muhammad says, "O Christian , O Jew, you did not know Moses and Jesus well. Come and see me so that you may know them." The prophets all make each other known. The words of the prophets explain and clarify each other.
After that, the Companions said, "O Messenger of God! Every prophet make known him who came before him. Now you are the Seal of the Prophets. Who will make you known?"
He said: "He who knows his soul knows his Lord. In other words, He who knows my soul knows my Lord."
