Muslim ruler with a dried grape (7)
I believe the answer is:
sultana
'dried grape' is the definition.
(I've seen this before)
'muslim ruler with a' is the wordplay.
'muslim ruler' becomes 'sultan' (I've seen this before).
'with' says to put letters next to each other.
'sultan'+'a'='SULTANA'
(Other definitions for sultana that I've seen before include "Aunt Sal (anag)" , "Sovereign's mistress" , "Dried fruit - Muslim ruler's consort" , "Muslim ruler's wife perhaps" , "Dried white grape" .)
