The Ruling on Rejecting Ahad Hadiths in Matters of Creed

Question:
In the name of Allah. To you, Honorable Shaykh. This questioner says: If one rejects ahad hadiths and does not rely on them in matters of creed, does this constitute kufr (disbelief) that expels one from the religion?

Answer:
This is the creed of the Mu'tazilah and those who resemble them among the rationalists today. They are called rationalists because they rely on reason. This is misguided and erroneous. If one knows that the Messenger (peace and blessings be upon him) said this thing, he knows that the Messenger (peace and blessings be upon him) said it. If he says, as some writers do, "Even if the Messenger (peace and blessings be upon him) said it, this is kufr (disbelief)," because he is denying the Messenger (peace and blessings be upon him). However, if the authenticity of the chain is not established for him, he is excused due to ignorance. But if others know the authenticity of the chain and he does not, he is excused due to ignorance.
As for if he knows the authenticity of the chain and says, "Even if the Messenger (peace and blessings be upon him) said it," because some say, "I do not act upon this because it contradicts reason. Even if the Messenger (peace and blessings be upon him) said it, it contradicts reason," this person is a disbeliever without doubt, because he is denying the Messenger (peace and blessings be upon him).
