Is this a Shia narration?

[Optimus Prime]

A Rafidhi [a person who rejects the Khilafa of Abu Bakr and Umar] said to him [Al Hasan ibn Hasan], "Did not the Messenger of Allah say to Ali 'If I am Maula of someone , Ali is his Maula?'" He (Al Hasan) replied, "By Allah, if he meant the by that Amirate and rulership, he would have been more explicit to you in expressing that, just as he was explicit to you about the prayer, Zakat and Hajj to the House. He would have said to you, 'Oh people! This is your protector after me.' The Messenger of Allah gave the best good counsel to the people. If the business [of Imamat] had been as you say it is, and Allah and His Messenger had chosen Ali for this matter after the Prophet, then he would have been the person with the gravest error and wrong action since this would mean either that he ignored what the Messenger of Allah commanded him to do, or he would have made excuses to the people for having done so."
