With regard to the presence of da‘eef (weak) hadiths in it, that is certain; in fact it even contains some mawdoo‘ (fabricated) hadiths.

Abdullah bin Ahmad bin Hanbal said: “I said to my father: Why do you dislike the writing of books, when you have made Al-Musnad?” He said: “I made this book as an Imaam, so that if the people disagree regarding the Sunnah of the Messenger of Allah, they may refer to it. [Khasa is al Musnad, p-2]
