Does the Salaf’s acceptance of ahad reports in matters of creed contradict the statement that creed is not built on probable evidence?

Question:
Honorable Shaykh, may Allah grant you success, you mentioned (may Allah preserve you) that certainty is required in creed, and mere suspicion is not sufficient. How do you reconcile this with the Salaf’s acceptance of ahad reports in matters of belief?

Answer:
My brother, my brother, an authentic ahad report provides certainty. The one who says it provides only suspicion is speaking the words of the Mu'tazilah. They are the ones who say that ahad reports provide only suspicion. That is wrong. Rather, if a hadith is authentic, whether it is mutawatir or ahad, it provides knowledge and certainty. Yes. As for their claim that it provides only suspicion, that is false. That is the speech of the Mu'tazilah, the Asha'irah, and those similar to them. As for the people of the Sunnah and the community, they hold that whatever is authentic from the Messenger of Allah (peace and blessings be upon him), or from Allah, or from the Messenger of Allah (peace and blessings be upon him), provides knowledge and certainty. Yes.
