Teacher from Islamabad (4)
I believe the answer is:
lama
'teacher' is the definition.
(a lama is a spiritual teacher in Buddhism)
'from islamabad' is the wordplay.
'from' indicates a hidden word.
'LAMA' can be found hidden inside 'islamabad'.
(Other definitions for lama that I've seen before include "Religious leader" , "A Buddhist priest in Tibet (4)" , "Tibetan high priest" , "A Tibetan Buddhist priest or monk" , "A Buddist monk in Tibet" .)
