Indian believer (5)
I believe the answer is:
hindu
'indian believer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hindu that I've seen before include "Adherent of an Asian religion" , "Indian religious follower" , "Man of religion" , "Follower of India's main religion" , "Brahma is one of his gods" .)
