Idrís

An imagining of Idris visiting Heaven 
and Hell

ʾIdrís is an ancient prophet and patriarch mentioned in the Qur'an, whom Muslims believe was the third prophet after Adam (as) and his son Sheath (as). Islamic tradition has unanimously identified Idris with the biblical Enoch, although many Muslim scholars of the classical and medieval periods also held that Idris and Hermes Trismegistus were the same person.

He is described in the Qur'an as "trustworthy" and "patient" and the Qur'an also says that he was "exalted to a high station", Because of this and other parallels, traditionally Idris has been identified with the Biblical Enoch, and Islamic tradition usually places Idris in the early Generations of Adam, and considers him one of the oldest prophets mentioned in the Qur'an, placing him sometime between Adam and Noah. Idris' unique status inspired many future traditions and stories surrounding him in Islamic lore.

According to a hadith [tradition], … it is said that on Muhammad's Night Journey, he encountered Idris in the fourth heaven. The traditions that have developed around the figure of Idris have given him the scope of a prophet as well as a philosopher and mystic, and many later Muslim mystic or Sufis… also mentioned having encountered Idris in their spiritual visions.
