Question:
He says: Honorable Shaykh, may Allah grant you success, some scholars say that acting upon the Book and the Sunnah requires that it be in accordance with the understanding of the righteous Salaf. What is the evidence for this?

Answer:
Is it in accordance with the understanding of the righteous Salaf? That means we do not contradict them. It is not necessary that it exactly matches their understanding, but we do not contradict them. This is what "in accordance with the understanding of the righteous Salaf" means: that we do not contradict them by bringing something new that contradicts what the righteous Salaf were upon. Yes.
