When the Deed of the Messenger (peace and blessings be upon him) Is Specific to Him

Question:
When is the saying of the Messenger (peace and blessings be upon him) given precedence over his deed, and when do we say that this is specific to the Messenger (peace and blessings be upon him) and not to others?

Answer:
Answer: Whatever is established from the Messenger (peace and blessings be upon him), whether in speech, deed, or approval, is the Sunnah of the Messenger (peace and blessings be upon him), which we are commanded to follow. If the Messenger (peace and blessings be upon him) commands something and acts contrary to it, we take the saying of the Messenger (peace and blessings be upon him) and interpret the deed of the Messenger (peace and blessings be upon him) as being specific to him, specific to the Messenger (peace and blessings be upon him).
