1) I remember hearing in a lecture once that it was said by Imam Jafar Sadiq (as) each of the prophets had a portion of Allahs knowledge, and gave examples such as Isa (as) had this much, Nuh (as) had this much, Ibrahim (as) had so and so and kept going up in number. Until he named Rasolullah (saw) and Imam Amir al-mu’minin (as), who had 72 out of 73 portions of Allahs knowledge. Is this a true hadith or a known hadith at all? If so where can I find it?

2) Is it true that both Salman al farsi (as) and Abu Dharr al ghafari (as) where both part of the ahlul bayt, as I have read certain narrations that both Imam Ali (as) and Rasolullah (saw) has stated that they are part of the ahlul bayt?

1) Allah’s knowledge can not be quantified. What we have in our narrations is that each prophet had portions of the 73 letters of Allah’s grand name.

2) Yes I have heard the narration that Salman is from us Ahlul Bayt. But I have not heard this about Abu Thar, but I would not find it improbable to be the case.
