Abadan's land (4)
I believe the answer is:
iran
'abadan'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 "Farsi-speaking country" , "Previously known as Persia" , "Modern-day Persia" , "Former Persia" , "Islamic republic on the Persian Gulf" .)
