This study investigates the concept of Tadlis (concealment) according to early Hadith scholars and Ibn Hajar al-Asqalani, As for early Hadith scholars, they commonly call the Hadith narrator Mudallis meaning that he did not hear the Hadith from his contemporary teacher, Ibn Hajar, in his book Tabaqat al-Mudallisin defines Tadlis as the narrator’s narration from a teacher whom he had met but did hear from him using term that indicate the possibility of hearing that Hadith or otherwise, to this can be attached the narrations from those teachers whose contemporary students just met them and did not join their Hadith classes. Even though, early Hadith scholars call the narration of the two contemporary narrators, who never met or have mutual narration Tadlis. Ibn Hajar sees that this is called concealed Mursal (loose) narration, by doing this he differs from early hadith scholars who did not distinguish between the two forms of narration. Ibn Hajar says” if he narrates from a contemporary whom he never met using formula that indicates its possibility or otherwise, then it is a concealed Mursal (loose) narration, some considered it a Tadlis (concealment), it is preferable to distinguish between these form”.
