I believe the answer is:

This is all the clue.
(Other definitions for alabama that I've seen before include "US state on the Gulf of Mexico" , "US state in which Birmingham is situated" , "US state west of Georgia" , "American state, capital Montgomery (7)" , "US state known as the Heart of Dixie" .)
