Majhūl al-ʿayn is a narrator who is named but whose person remains insufficiently known, with only one pupil transmitting from him.
• His name is stated.
• Only one person transmits from him.
• Merely supplying a name does not necessarily remove jahālah.
His report is unreliable unless his reliability is established through some means.
