Islamic creed and Imamate succession in Shia belief

“Welcome, O Abu al-Qasim, you are surely our disciple.” “O son of the Messenger of Allah,’ I said, “I want to provide my beliefs before you. If they are right, I will maintain until I meet Allah, Powerful and Majestic is He.” “Well,” said the Imam (a) “show me.” I began, “Allah, Blessed and Exalted is He, is One. There is nothing like Him. He is out of the two edges-the edge of neutralization and the edge of anthropomorphism.He is not corporeality, image, accident, or essence. He, Glorified is His Name, is the Maker of the corporalities, the Former of the images, and the Creator of the accidents and the essences. He is the Lord, the Possessor, the Maker, and the Producer of everything. He is All-wise; He neither does the ugly nor does He break the obligatory. I also believe that Mohammed (s) is His servant and messenger as well as the seal of the prophets. No prophet will come forth after him up to the Day of Resurrection. His code is the seal of codes. No code will be enacted after his code up to the Day of Resurrection. I also believe that the Imams, successors, and lawful leaders after him are Amir ul-Mu’minin Ali bin Abi Talib, al-Hasan, al-Hussein, Ali bin al-Hussein, Mohammed bin Ali, Ja’far bin Mohammed, Musa bin Ja’far, Ali bin Musa, Mohammed bin Ali, and you-my master, peace be upon you all, respectively.” The Imam (a) said: “After me, my son al-Hasan will come. What will people do with his successor?” “What is that, master?” I asked. Imam al-Hadi (a) answered: “His appearance will not be seen and his name cannot be mentioned until he comes forth to fill in the earth with justice and fairness in the same way as it would be filled with wrong and injustice.” “I submit to this,” I said, “I also declare that the follower of the Imams is surely the disciple of Allah, their enemy is surely the enemy of Allah, the obedience to them is surely the obedience to Allah, and the disobedience to them is surely the disobedience to Allah. I declare that the Prophet’s Midnight Ascension is right, the tomb interrogation is right, Paradise is right, Hell is right, the Path is right, the Balance is right, and there is no doubt about the coming of the Hour of Doom and that Allah will raise every one from the graves. I declare that the obligatory religious duties, after the (obligatory) loyalty to the Imams, are the prayer, the zakat, the fasting, the hajj, the jihad, the enjoinment of good, the forbiddance of evil, and the keeping of the parents’ rights. This has been my religion, belief, and faith.” Ali bin Mohammed (a) said: “O Abu al-Qasim, this is, by Allah, the very religion that Allah has accepted for His servants; therefore, you should keep it. Allah may strengthen your faith by the true Words in this world and in the life to come.”
