Abu Said al Khudri reports: "We sat waiting for the Messenger of Allah (pbuh&hp) when he came out to meet us. The strap of his sandal was broken and he tossed it to Ali. Then he (pbuh&hp) said: "A man amongst you will fight the people over the tawil (interpretation) of the Quran in the same way as I have fought over its tanzil (revelation)." Thereupon Abu Bakr said, 'Is that I?' The Prophet (pbuh&hp) said: "No." Then Umar asked him, 'Is that I?' "No." said the Prophet (pbuh&hp). "It is the mender of the sandal (i.e. Ali)."

"Fourteen thousand years before Adam, upon whom be peace, was created, I and Ali were a light in the presence of God. When God created Adam, upon whom be peace, He divided it into two parts. I am one of the parts and Ali is the other part."
