It has been narrated to us by Ali Bin Ismail, from Musa Bin Talha, from Hamza Bin Abdul Muttalib Bin Abdullah Al-Ju’fy who said:

"I came up to Al-Reza (as) and with Me was a Parchment, or a paper, in it (was written) from Imam Jafar Sadiq (as) that; "The example of this world to the Master of this Command, is like the example of a segment of a walnut". The Imam (as) said, "O Hamza, by Allah (swt) that is the truth. Transfer it to a surface (make a copy of it)."It has been narrated to us by Muhammad Bin Al-Husayn, from Musa Bin Sa’dan, from Abdullah Bin Al-Qasim, from Sama’at Bin Mahraan who said:

Abu Abdillah Imam Sadiq (as) said, "That the example of the world, for the Imam (as), is like the segment of a walnut. Whenever something occurs in it, He takes from it, or from its outskirts, just like one of you takes from above the table whatever you like. Nothing of it is hidden from Him."
