Temples being quiet, with an idol, a bit of silver? (7)
I believe the answer is:
pagodas
'temples' is the definition.
(pagoda is a kind of temple)
'quiet with an idol a bit of silver?' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'with' is a charade indicator (letters next to each other).
'an' becomes 'a'.
'idol' becomes 'god' (synonyms).
'bit of' indicates taking the first letters.
The first letter of 'silver' is 's'.
'p'+'a'+'god'+'a'+'s'='PAGODAS'
'being' acts as a link.
(Another definition for pagodas that I've seen is " temples".)
