Lawful to you is the pursuit of water-game and its use for food,- for the benefit of yourselves and those who travel; but forbidden is the pursuit of land-game;- as long as ye are in the sacred precincts or in pilgrim garb. And fear Allah, to Whom ye shall be gathered back.
Depending on their habitats, animals are of two kinds: either marine or terrestrial. Marine animals, that is, those which live in water and cannot survive outside it, are all halal. It does not matter in what way they are obtained: whether they are taken out of the water dead or alive, whole or in pieces, whether they are fish or marine animals, whether they are called sea dogs or sea hogs, or whether they are caught by a Muslim or a non-Muslim. The Most Generous Lord has opened wide His bounty upon His servants by permitting them to eat all marine animals, without the requirement of bleeding; man has been left free to catch them in whatever manner he is able, avoiding any unnecessary cruelty as far as possible. Reminding us of His favors, Allah Ta’ala says, And it is He Who has subjected the sea (to you) in order that you may eat fresh meat from it…. (16:14)
The game of the sea is permitted to you and so is its food, a provision for you and for travelers by sea…. (5:99 (96))
Praise be to Him for not having excluded anything, for Thy Lord is not forgetful. (19:64)
