Worshipper in Alhambra staring (5)
I believe the answer is:
rasta
'worshipper' is the definition.
(I've seen this before)
'in alhambra staring' is the wordplay.
'in' indicates the answer is hidden within the clue.
'RASTA' is hidden in the letters of 'alhambra staring'.
(Other definitions for rasta that I've seen before include "Dreadlocked devotee" , "religious follower" , "Member of WI religion" , "Religious adherent" , "Disciple" .)
