‘In fact, he (a.s.) has died.’ Ali ibn Hamza asked, ‘Who has your father (a.s.) introduced to succeed him?’ The Imam (a.s.) replied, ‘Me.’ Ali ibn Hamza said, ‘You aresaying what none of your forefathers starting with Ali ibn Abi Talib (a.s.) and those who came after him have said.’ The Imam (a.s.) said, ‘But the best and the noblest of my forefathers who is the Prophet of God (a.s.) has said that.’ Ali ibn Hamza said, ‘Don’t you feel threatened by this tribe (the Abbasids) and aren’t you afraid of them?’ The Imam (a.s.) said, ‘If I fear them, I have assisted them against me. Abu Lahab went to the Prophet of God (a.s.) and threatened him. God’s Prophet (S) told him, ‘If I should fear you in the least, I have lied. I have lied about my Prophethood.’ This was the first sign of the Prophet of God (a.s.). This is also my first sign for you. I have lied if Harun harms me in the least.’ Al-Husayn ibn Mihran said, ‘You have done what we want when you publicly announce your Divine Leadership.’ The Imam (a.s.) asked that man, ‘Do you want me to go to Harun in person and tell him that I am the do this in the beginning of his call. The Prophet (S) only Divine Leader and he is nothing? The Prophet of God (a.s.) did not inform his near relatives, friends and trusted friends about his Prophethood, and invited them to accept Islam. The Prophet (S) did not invite all the people. You have accepted the Divine Leadership of my forefathers and think that Ali ibn Musa (a.s.) is denying his father being alive due to the concealment of faith. But how is it that I announce my Divine Leadership to you without any concealment of faith, and openly declare that I am the Divine Leader? If my father (a.s.) was alive, how could I hide it from you and tell you that he (a.s.) has passed away?’”The author of this book (a.s.heikh Sadooq) - may God have Mercy upon him - said, “The reason why the Imam (a.s.) did not fear (Harun) Ar-Rashid was due to the Covenant he had in which his murderer was declared to be Al-Ma’mun and no one else.”
