Old man has hurt Muslim dignitary (5)
I believe the answer is:
pasha
'muslim dignitary' is the definition.
(I've seen this before)
'old man has hurt' is the wordplay.
'old man' becomes 'pa' (both can mean father).
'hurt' indicates anagramming the letters.
'has' with letters rearranged gives 'sha'.
'pa'+'sha'='PASHA'
(Other definitions for pasha that I've seen before include "Turkish high-ranker" , "High ranking Turkish official or officer" , "Turkish title" , "Muslim dignitary" , "High-ranking Turk" .)
