 1. Ali ibn Ibrahim has narrated from his father from ‘Abd al-‘Aziz ibn al-Muhtadi from ‘Adallah ibn Jundab to who Imam al-Rida  wrote the following. “Thereafter, (thanking Allah) Muhammad (s.a.) was the trustee of Allah for His creatures. When he was taken away from this world we, Ahl al-Bayt inherited him, thus, we are the trustees of Allah over His earth. With us is the knowledge of the sufferings, the death, the genealogy of the Arabs and the birth of Islam. We know the man when we see him in the truth of faith or hypocrisy. Our followers (Shi‘a) are listed (with us) by their names and the names of their fathers. Allah has established a covenant with them and with us. They land wherever we would do so and enter wherever we would enter. There is no besides us and our followers as living the Islamic culture. We are the noble saviors and the descendents of the prophets and of the children of the successors of the prophets. We the ones to whom the book of Allah, the Most Holy, the Most High, has come exclusively. We, of all people, have the first priority (closeness) to the book of Allah. We, of all people, have the first priority (closeness) to the Messenger of Allah. For us He formed His religion. “He has established for you (family of Muhammad) a form of religion which is of the commands to Noah {we are commanded with whatever Noah was commanded}. It is of the mattes that We have revealed to you (Muhammad) and of the commands to Noah, Abraham, Moses, and Jesus to follow.{We have taught and preached the knowledge that was taught to us. We were given the knowledge of these prophets. We are the heirs of the commissioned Messengers}. (He has explained it) so that you (family of Muhammad) would be steadfast and united (all in a united group) in your religion. What you call the polytheists {polytheists in the acknowledgement of the Divine authority of Imam Ali (a.s.} to{the acknowledgement of the Divine authority of Imam Ali (a.s.}is extremely grave for them. God {O Muhammad} attracts to (the religion) whomever He wants and guides to it whoever turns to Him in repentance.” (42:13)
