What is the meaning of Ibn Abi Hatim’s statement about a narrator: “Shaykh”?

The questioner : Ibn Abi Hatim or someone else says, for example, “Shaykh.” Is this someone whose hadith is recorded?

The Shaykh : “Shaykh”?

The questioner : He says only “Shaykh.”

The Shaykh : It is not known exactly what it means; rather, that is understood by looking at the narrators from him. In other words, if a group of people narrated from him and he was described as a “Shaykh,” then his hadith can be considered and used as evidence. However, if only one person narrated from him and he was still described as a “Shaykh,” then his status is that of an unknown narrator. Sometimes he is strengthened by other narrations, and sometimes he is not.
