Combining the two hadiths and explaining that they are two separate cases, detailing the benefits of the hadith, and explaining the meaning of the statement, "Whoever turns away from my Sunnah is not one of me."

The Shaykh : Look at this case. The Prophet (peace and blessings be upon him) came to them. It appears, and Allah knows best, that these are two cases, because the wording of al-Bukhari is: Then, there is a discrepancy regarding what they swore to. The narration of al-Bukhari says: And in this, agrees, and the second says: and the third: So it appears, and Allah knows best, that they are two cases. But in any case, the Prophet's (peace and blessings be upon him) eagerness to prevent extremism in the religion—he himself came to them and said this. Then he said, stating the ruling first: This sentence is emphasized by "ama," the oath, "inna," and the "lam," all of this to make it clear to them that fear of Allah and piety do not lie in being strict. Fear of Allah and piety lie in following the Sunnah of the Messenger (peace and blessings be upon him). He swore here, (peace and blessings be upon him), not to praise himself—far be it from him—but to prove to these people that they would not reach the level he had reached in fear of Allah and piety. And yet, his practice, compared to what they wanted for themselves, was easy and less than that. He said, (peace and blessings be upon him): He did not specify fasting or breaking the fast. For this reason, the Prophet (peace and blessings be upon him) sometimes fasted until it was said, "He does not break his fast," and sometimes he broke his fast until it was said, "He does not fast," because he followed what was easier and more beneficial. Perhaps his soul, for example, would not accept it; a person's soul might not accept fasting for some reason, so he does not fast, easing things for himself. And on some days, he is at ease with fasting and wants to fast, so he does so. Likewise, regarding sleep, sometimes the Messenger (peace and blessings be upon him) would sleep until he did not stand for prayer, and it was said, "He does not stand for prayer," and he would stand for prayer until it was said, "He does not sleep." This is not always the case, because most of the time, (peace and blessings be upon him), he would fast three days of every month. So, the Prophet (peace and blessings be upon him) made it clear to them that he combines walking
The student: Fasting and breaking the fast

The Shaykh : Fasting and breaking the fast, contrary to the one who said, "I fast and do not break my fast." Likewise, he said, (peace and blessings be upon him): Contrary to the one who said, "Yes, I stand for prayer and do not sleep, and I marry women," contrary to the one who said, "I do not marry women." So he made it clear, (peace and blessings be upon him), that this is his way. Then he said: Do you understand?
This may raise a question: Is the meaning of "whoever turns away" an absolute turning away, i.e., in everything he does, or in some things?
We know that the methodology of the people of the Sunnah and the community is based on detail. Whoever turns away from his Sunnah absolutely, then he is not one of him absolutely. And whoever turns away from his Sunnah in one thing but not another, then he is not one of him in that specific thing he turned away from. Then, there is also a distinction between one who turns away from the Sunnah of the Messenger (peace and blessings be upon him) out of disdain for it or out of laziness, while having a heartfelt desire for it. The first is in great danger of having his deeds nullified, as Allah the Exalted said: And this is in very great danger. The second is less severe, even though a person is commanded to follow the Sunnah absolutely, but it is less severe than a person who says, "I do not want this Sunnah." This is less severe, and perhaps Allah the Exalted will guide him. Now, if someone shaves his beard, does one stand up and say, "This man is not of the Prophet in any way"?
The student: No.

The Shaykh : No, it is not permissible. And I have been informed that some of the brothers stood as a preacher to the people, admonishing them, and he was strict about shaving the beard until he said, "Whoever shaves his beard is outside the Sunnah of the Messenger," and he stated this categorically. This is a mistake. So the detail is: First, whoever turns away from the Sunnah absolutely is a disbeliever and outside the Sunnah. And whoever turns away from one thing but not another is not of the Prophet (peace and blessings be upon him) in that specific thing he turned away from. Then, there is a distinction between one who turns away from the Sunnah of the Messenger out of dislike for it, and one who leaves it out of negligence. Between these two types of leaving, there is a great difference, a great distinction.
