I utter a couple of names when pushing back Hindu beggar (8)

'beggar' is the definition.
(I know that sannyasi is a type of beggar)

'i utter a couple of names when pushing back hindu' is the wordplay.
I cannot quite see how this works, but
'i' could be 'a' and 'a' is present in the answer.
'a' is present in the answer.
'names' could be 'nn' (an abbreviation for name twice) and 'nn' is located in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
