I'm a little stuck... Click here to teach me more about this clue!

'an iranian type many have faith in' is the definition.
I can't tell whether this defines the answer.

'turns up manuscript is about one type of music' is the wordplay.
'turns up' is a reversal indicator.
'manuscript' becomes 'ms' (abbreviation for manuscript).
'about' is an insertion indicator.
'one' becomes 'I' (Roman numeral).
'type of music' becomes 'rap' (music genre).
'i'+'rap'='irap'
'is' put inside 'irap' is 'iisrap'.
'ms'+'iisrap'='msiisrap'
'msiisrap' reversed gives 'PARSIISM'.
