Musnad Ahmad 1908
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
"Abdul-"Azeez bin Rufai" told us: Shaddad bin Ma"qil and I entered upon Ibn "Abbas, and Ibn ‘Abbas said: The Messenger of Allah (ﷺ) did not leave anything except what is between these two covers. We entered upon Muhammad bin "Ali and he said something similar. And al-Mukhtar used to say: the Revelation.
