Muslim legal expert's everyday clothing (5)
I believe the answer is:
mufti
This clue could be a double definition.
'muslim legal expert's' is the first definition.
(I've seen this before)
'everyday clothing' is the second definition.
'mufti' can be an answer for 'clothing' (mufti is a kind of clothing). I'm not certain of the 'everyday' bit.
Can you help me to learn more?
(Other definitions for mufti that I've seen before include "Civilian dress, worn by an off-duty soldier, say" , "officer of the law" , "Civilian dress, in army terms" , "Civilian dress (for serviceman)" , "Plain clothes - Muslim law expert" .)
