Q: Is it permissible to eat prawns?
A: According to the Hanafi School, from all the sea creatures only fish is permissible to consume. Hence, that which is not classified as a fish is impermissible. Therefore, it will not be correct to consume crabs, calamari and other crustaceans.
In terms of prawns, there is a difference of opinion amongst the Hanafi Jurists. Some classify it as fish and hence consider it Halal.
