The ruling on one who denies a well-known Sunnah, such as the miswak and the two rak'ahs of Fajr

Question:
He says: Honorable Shaykh, may Allah grant you success, if one rejects or denies a well-known Sunnah in the religion out of following one's desires, does that make him a disbeliever? For example, if he denies the Sunnah of using the miswak, or denies the two rak'ahs of Fajr.

Answer:
Yes, if he denies the miswak or any other established Sunnah, he becomes a disbeliever by doing so. If he denies a Sunnah and says, "Absolutely, the miswak is not prescribed; this is nonsense, this is play, and this," then he is a disbeliever, may Allah protect us from that, because the miswak is established from the Messenger (peace and blessings be upon him). He says: Honorable [Shaykh]. He says: The miswak is prescribed, and that is fine, but I am one who uses a toothbrush; I use a toothbrush, not a miswak. But if he says, "No, it is not prescribed; this is nonsense," this is lying about the Messenger (peace and blessings be upon him).
