Continuation of the discussion on the correct understanding of the saying of the Prophet (peace and blessings be upon him): “Whoever introduces a good practice in Islam”

The Shaykh : I also want to mention something else regarding the understanding of ; that is, whoever claims that something that occurred after the Prophet (peace and blessings be upon him) is good must provide evidence. I am now giving you a clear, well-known example. We all know that the Prophet (peace and blessings be upon him and his family) conquered the town of Khaybar by force, and he made a treaty with the Jews that they would remain there and work the land, its date palms, and ... and that the proceeds would be divided, with half for the Messenger (peace be upon him) and half for the Jews. Among the conditions he (peace and blessings be upon him) imposed in this treaty with the Jews was that he said to them: .
The Messenger of Allah (peace and blessings be upon him) passed away while the Jews were still in Khaybar. They continued to plot against him (peace be upon him) and attempt to kill him, even by poisoning the fat, as it is said, and as came in the story of the Jewish woman who gifted the Prophet (peace and blessings be upon him) a sheep’s leg. A Companion or two died as a result of eating it, but the Messenger (peace be upon him) spat it out. However, he continued to complain of its effects until he felt its pain in the illness of his death (peace be upon him). The Jews remained in Khaybar until after the death of the Messenger, throughout the caliphate of Abu Bakr, and part of the caliphate of 'Umar. Then 'Umar decided to expel them from Khaybar, so he expelled them and gave them notice before their expulsion. Now we say—and this is a great branch of jurisprudence: Is this expulsion of the Jews by 'Umar ibn al-Khattab an innovation, or is it a good practice, or is it a bad practice?
The answer: This incident, first of all, has no relation to the “good innovation” in the terminology of the later scholars; rather, it has a relation to the “good practice” in the terminology of the Master of the Messengers, whose saying you heard in the previous hadith.
I asked earlier: We have another way to object to the innovators who praise some innovations by citing this hadith. We say to them that rational good and evil are not part of the methodology of the people of the Sunnah; rather, we know good and evil by the Shari'ah. So if someone says: “This is a good matter,” we say to him: “Bring the evidence?”
Now we have brought up a matter that occurred after the Messenger (peace be upon him), and there is absolutely no doubt about that; that is, 'Umar’s expulsion of the Jews from Khaybar. Is this an innovation in the sense of something newly invented, or is it a good practice? There is no doubt that the answer is that it is a good practice. How did we know that this is a good practice? From what we mentioned earlier, when the Prophet (peace and blessings be upon him and his family) made a treaty with the Jews on the terms previously explained, he said to them: . We Muslims, so 'Umar came and saw the benefit in expelling them, so he expelled them, thereby executing the will that the Messenger (peace be upon him) mentioned in one of the conditions he imposed on them. Thus, 'Umar did not innovate anything in Islam here.
