Fit to eat, to Muslims (5)
I believe the answer is:
halal
'fit to eat to muslims' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for halal that I've seen before include "(Meat from animals killed) according to Muslim law" , "specially-prepared meat" , "lawfully killed" , "Meat eaten by Muslims" , "(Of meat) suitable for Muslims" .)
