To whom do the Hadith scholars apply the term "Majhūl al-Ḥāl" (unknown in status), and what is the majority's view on accepting narrations from him?

The unknown narrator in hadith terminology is of two types: majhooul al-ain (unknown person), who is someone whose person is not known, and majhooul al-hal (unknown condition), who is someone whose person is known but whose scholarly status is unknown. The narration of an unknown person, of either type, is not accepted unless the anonymity is removed, because this knowledge is religion, so one looks to the people of Sunnah and accepts their hadith, and to the people of innovation and does not accept their hadith.
