Returning, I object - really furious about this Muslim region (7)
I believe the answer is:
emirate
'this muslim region' is the definition.
'emirate' can be an answer for 'region' (emirate is a kind of region). I am not certain of the 'this muslim' bit.
'returning i object really furious' is the wordplay.
'returning' says the letters should be written in reverse.
'i object' becomes 'me'.
'really furious' becomes 'irate' (I've seen this before. I am not sure about the 'really' bit.).
'me' backwards is 'em'.
'em'+'irate'='EMIRATE'
'about' acts as a link.
Can you help me to learn more?
(Other definitions for emirate that I've seen before include "Independent Islamic state" , "Arab state" , "Arab domain" , "Abu Dhabi, perhaps" , "Meatier (anag) -- Qatar, for example" .)
