I believe the answer is:

sufic

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

'ascetic?' is the definition.
(I've seen this before)

I can't explain the rest of the clue.

(Other definitions for sufic that I've seen before include "ascetic?" , "Relating to some Muslim mystics" , "Mystic" .)

I've seen this clue in The Times and The Sunday Times.
