2. [2/-] The Treatise on the ‘Status of the Narrations of our Companions and Establishing their Authenticity’ authored by Sa’d b. Hibat Allah al-Rawandi: al-Saduq from his father from Sa’d b. Abdallah from Ayyub b. Nuh from Muhammad b. Abi Umayr from Abd al-Rahman b. Abi Abdillah who said:

al-Sadiq عليه السلام said: if there comes to you two divergent Hadith then compare them with the book of Allah, then take the one which agrees with the book of Allah and reject the one that opposes the book of Allah, so if you do not find anything to do with them in the book of Allah then compare both to the reports of the Amma, so the one that agrees with their reports then leave it, and the one that opposes their reports then take it.
