Salam is it true that shrimps(prawns)calamari and lobster are not halal?and why?please help me
according to Imam Shafi, they are fine to eat, as he classifies such animals to be under the quranic verse: احل لکم صید البحر (the sea animals are allowed for you).
According to Imam Abu Hanifa and other Hanafi Imams, this verse is talking about fish, so fish are allowed but not prawns etc.
thus, whether you eat them or not depends on which imam you follow.
The ruling is not that strict though, and i know of hanafi Ulema who have prawns, and have no issues with eating them.
