Muhammad b. Yahya from Ahmad b. Muhammad from Safwan b. Yahya from `Isa b. as-Sariy Abu’l Yasa`. He said: I said to Abu `Abdillah عليه السلام: Inform me of the principles of Islam; those which no one can fall short in their recognition of a thing from them, those which if anyone were to fall short in their recognition of a thing from them he would corrupt his religion and his deeds would not be accepted. Those which, if one were to recognize them and act by them, his religion would be correct and his deeds would be accepted; and they would not tighten for him from that which he is ignorant of. So he said: The testimony that there is no god except Allah, and faith that Muhammad is the Messenger of Allah صلى الله عليه وآله, and the confirmation that what he had brought was from Allah, and that [the payment of] the money of zakat is a right, and [holding to] the wilaya that Allah عزوجل has ordered – the wilaya of the Family of Muhammad صلى الله عليه وآله. He said: So I said: Is there anything in the wilaya that is exclusive in virtue for one that holds to it? He said: Yes, Allah عزوجل says: “O you who believe! Obey Allah and obey the Messenger and those in authority from amongst you” (4:59). And the Messenger of Allah صلى الله عليه وآله said: Whoever dies without recognizing his Imam has died the death of jahiliyya. That [imam] was the Messenger of Allah صلى الله عليه وآله, then it was `Ali عليه السلام, while the others said, “That was Mu`awiya”. Then it was al-Hasan, then it was al-Husayn, while others said, “Yazid b. Mu`awiya and Husayn b. `Ali”, while they are not equal, they are not equal.He said: Then he was silent. Then he said: Shall I elaborate for you? Hakam al-A`oor said to him: Yes, may I be your ransom. He said: Then it was `Ali b. al-Husayn, then it was Muhammad b. `Ali Abu Ja`far. Before Abu Ja`far, the Shi`a did not know the rules of Hajj, nor of what was permissible for them or what was forbidden for them, until Abu Ja`far; so he opened for them and explained to them the rules of Hajj and what was permissible for them and what was forbidden for them, until the people needed them after they had needed the people. And this is the affair – the Earth does not remain without an Imam, and whoever dies without recognizing his Imam has died the death of jahiliyya. The time when you will need it (i.e. wilaya) most urgently is when you find yourself here – and he pointed at his throat – and the world has been cut off from you, and you say, “I was upon a good affair”.And a similar hadith was narrated from Abu `Ali al-Ash`ari from Muhammad b. `Abd al-Jabbar from Safwan from `Isa b. as-Sariyy Abu’l Yasa` from Abu `Abdillah عليه السلام.
(sahih) (صحيح)
It seems hadith by similar wording has been narrated by more than one chain, and that's two that are sahih. Allahu Akbar! Allahuma sale ala Muhammad wa als Muhammad.
