How did the author say, "The evidence by which the names of Allah the Exalted and His attributes are established are the Book and the Sunnah," when he mentioned only two proofs, and are they taken from the Companions?

The Shaykh : This principle is also important: the evidence by which the names of Allah and His attributes are established are the Book of Allah and the Sunnah of His Messenger (peace and blessings be upon him and his family). I have a difficulty with the phrasing: "the evidence," yet he mentioned only two things?
The answer is that this is like the saying of Allah the Exalted: The meaning of "evidence" is the genus. How many proofs are in the Book? Hundreds of proofs. Likewise, the Sunnah. The names of Allah and His attributes are not established by anything other than these two. If someone asks: "If something comes to us from the Salaf, specifically from the Companions, do we affirm it or not?" The rule among scholars of terminology is that if this Companion is known for taking from the Children of Israel, we do not accept his statement, because these are matters of the unseen in which the intellect has no role, so that we might say this is his opinion. But if he is not known for taking from the Children of Israel, we accept his statement, not as his own opinion, but as having the ruling of being elevated to the Prophet.
Scholars of terminology have mentioned that what is reported from a Companion regarding matters in which the intellect has no role, and where he is not known for taking from the Children of Israel, has the ruling of being elevated to the Prophet, such as the rulings of the Day of Resurrection, the reports of the Day of Resurrection, and the like.
