Mufti's cryptically welcoming bishop with quiet greeting (4,4)

'greeting' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'mufti's cryptically welcoming bishop with quiet' is the wordplay.
'cryptically' indicates an anagram.
'welcoming' indicates putting letters inside (in sense of 'inviting in').
'bishop' becomes 'b' (chess abbreviation).
'with' means one lot of letters go next to another.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'muftis' is an anagram of 'fistum'.
'fistum' placed around 'b' is 'fistbum'.
'fistbum'+'p'='FIST BUMP'
