Hadith Al-Muqatalah

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).”
