The full answer
If there is a genuine reason to doubt whether meat is Zabiha, verify it before eating it.
HMS cites the Prophetic guidance:
“Leave that which causes you doubt for that which does not cause you doubt.”
Ask about the supplier, slaughter method and certification rather than simply assuming.
HMS specifically advises consumers not to eat meat when its Zabiha status cannot be established.
