Collect wig that's used in mosque (6,3)

I believe the answer is:

prayer rug

'that's used in mosque' is the definition.

'collect wig' is the wordplay.
'collect' becomes 'prayer' (I've seen this before).
'wig' becomes 'rug' (rug is a slang term for a wig).
'prayer'+'rug'='PRAYER-RUG'

(Another definition for prayer rug that I've seen is " appeals to master from here?".)

I've seen this clue in The Times.
