Muslim with Parisian is most genial (8)

I believe the answer is:

sunniest

'most genial' is the definition.
(I've seen this before)

'muslim with parisian is' is the wordplay.
'muslim' becomes 'sunni' (Sunni is an example).
'with' says to put letters next to each other.
'parisian is' becomes 'est' ('is' in French).
'sunni'+'est'='SUNNIEST'

(Another definition for sunniest that I've seen is " most genial".)

I've seen this clue in The Telegraph.
