What is the ruling on one who doubts a hadith whose chain of narration is authentic?

Question:
Honorable Shaykh, may Allah grant you success, you touched on the matter of one who doubts the pure Sunnah, stating that this is a doubt in the Shari'ah. So what is the ruling on one who doubts a hadith found in Sahih al-Bukhari or in Sahih Muslim?

Answer:
The ruling applies to him if he doubts an authentic hadith. Whether it is in al-Bukhari or in Muslim, or even if it is in other than the two Sahihs, as long as its chain of narration is authentic, it is not permissible to doubt it, because it is the speech of the Messenger of Allah (peace and blessings be upon him), and it is not permissible to doubt the speech of the Messenger. The one who does not speak from desire (peace and blessings be upon him) means that if it contradicts your desire or contradicts your wish, you doubt it, or if it contradicts the wish of so-and-so or so-and-so, you doubt it; this is not permissible. Yes.
