What do you say about this statement from Al-Shaafi’i r.a?

Al-Shaafi’i, may Allaah have mercy on him, said: “I do not know of anyone among the Sahaabah and Taabi’een who narrated a report from the Messenger of Allaah (peace be upon him) without accepting it, adhering to it and affirming that this was sunnah. Those who came after the Taabi’een, and those whom we met did likewise: they all accepted the reports and took them to be sunnah, praising those who followed them and criticizing those who went against them. Whoever deviated from this path would be regarded by us as having deviated from the way of the Companions of the Prophet (peace be upon him) and the scholars who followed them, and would be considered as one of the ignorant.
