Are the hadiths that Muslim narrated in the introduction considered to be in the Sahih?

The questioner : Are the hadiths that he narrated in the introduction considered to be in the Sahih?

The Shaykh : This chain of narration is valid, because he provided the chain. If he had only said, "This is the famous report from the Messenger of Allah (peace and blessings be upon him) ," and stopped there, we would say it is not valid in his view. But because he provided the chain afterwards, it became like what is in the body of the Sahih. Yes, Mansur.
