‘Abd-ul-Karim ibn-i Ab-il-‘Awja’ is among those individuals who were known as atheists in the 2nd century A.H., 8th century AD. He would enter holy Muslim places and freely express his opinions without fear of any retribution.

Discussing the creed and beliefs of Ibn-i Ab-il-‘Awja’, this paper also studies his debates with Imam as-Sadigh (A).
