I want to know which Sea animals are halal and haram,,,,and whether Shrimp and octopus are halal or haram according to Hanafi Fiqh.
According to Hanafi Fiqh, fish of all kinds (species) is Halal to eat without any doubt. Any other sea creatures are not Halal to eat in accordance with the precepts of Hanafi Fiqh.
Octopus, lobster, crab would certainly be Haram according to Hanafi Fiqh but there are two opinion among the Hanafi scholars regarding shrimp. Some scholars say it is Halal because it is one of the species of fish and others say it is Haram because it is not a fish.
Due to the difference of opinion amongst the scholars of Hanafi Fiqh, the preferred opinion is that the shrimp is Makrooh at the most and Halal otherwise.
Hence, if someone eats shrimp, he should not be criticized and scorned. It is permissible to eat shrimp in my understanding.
And Allah knows best.
