It is narrated from Abdul Aziz bin Rufa’i, he says: I and Shaddad bin Ma’qil both went to the service of Sayyiduna Ibn Abbas (may Allah be pleased with him), he said: The Messenger of Allah (peace and blessings be upon him) has left nothing except what is between these two covers. (i.e., the Noble Qur’an) And we went to the service of Muhammad bin Ali, and he also said the same. Abdul Aziz said that Mukhtar bin Thaqafi used to claim that revelation was sent down to him.
