It is narrated from Sayyiduna Hubshi bin Junadah (may Allah be pleased with him) that he heard the Messenger of Allah (peace and blessings be upon him) say: "Ali is from me and I am from Ali, and no one can convey (my message) on my behalf except me and Ali."
Imam al-Tabarani (may Allah have mercy on him) said: Abu Bakr bin Abi Shaybah added in his narration that Sharik said: I asked the narrator Abu Ishaq: O Abu Ishaq! Did you see him (Hubshi)? He said: He came and stood by us in our gathering and narrated this hadith to us.
