The claim that Sahih al-Bukhari and Sahih Muslim contain weak hadiths

Question:
In this era, some claimants of knowledge have spoken about there being non-authentic hadiths in Sahih al-Bukhari and Muslim. Is this correct?

Answer:
It is not correct. The two books are great and authentic, and the Ummah accepted them. The people of knowledge accepted them with acceptance and submission. So they are two great and authentic books, except for a few words that may be objected to with other evidence from the same Sahih. Some words in which some narrators may have erred, but the text itself is authentic.
So the hadiths are authentic and accepted. It is obligatory to act upon them, except for one hadith—as far as I know—which occurred in Sahih Muslim, and some error occurred in it. Not all of it is error, but some error occurred in it. It is the hadith of Abu Hurayrah from the Prophet (peace and blessings be upon him) that he said: Then he counted, making the creation in seven days, from Saturday to Friday. The scholars have preserved that this is a mistake by some of the narrators. It is actually from Ka'b al-Ahbar, not from Abu Hurayrah. But it is from Ka'b al-Ahbar, so Ka'b erred in that. So this is a mistake in attributing it to the Prophet, and it is actually from the words of Ka'b al-Ahbar, so some of the narrators erred in it.
This occurred in Sahih Muslim, and the knowledge of the inauthenticity of its text is indicated by the Book of Allah and the Sunnah of His Messenger (peace and blessings be upon him), which show that Allah created the creation in six days, not in seven days. So an error occurred in mentioning that He created the earth on Saturday. The correct view is that the first of the creation was on Sunday, and it ended on Friday, six days. So I do not know of anything ruled as inauthentic except this hadith.
There are other words that occurred in Sahih Muslim, but not in the original hadith, rather in some of the words, such as in the prayer of the eclipse: that the Messenger (peace and blessings be upon him) bowed three times or four times in some of the rak'ahs. This is the ruling of al-Bukhari and a group of scholars that it is a mistake.
And the correct view is that he only bowed twice in each rak'ah. But this is not a matter of consensus, rather it is a point of disagreement among the people of knowledge: did the mention of three or four bowings become authentic or not? And this occurred in Sahih Muslim—may Allah have mercy on him.

In conclusion: That these two books are authentic in general and accepted, and there is no hadith in them that is unanimously agreed to be invalid, except the hadith of Abu Hurayrah that I mentioned to you, which is the error in counting the days only.
