Ayatollahs' land (4)
I believe the answer is:
iran
'ayatollah's land' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for iran that I've seen before include "Previously known as Persia" , "Modern-day Persia" , "Middle East Islamic republic" , "Country where the official language is Farsi" , "Asian country" .)
