Similarly, the details of the ‘good’ and ‘tender’ meat of species living either on land or sea or on both, i.e., Frogs , American Alligators , Beavers, Crabs, Walruses, and Penguins, are to be found in Ahadith for separating the permissible(s) from forbidden. We also need to turn to Ahadith to clarify the forbidden parts of the permissible species, which are unsuitable for consumption. In addition, to understand the rulings on slaughtering and catching fish (alive) from the sea.
Like the seafood, the permissibility of the meat and ‘parts’ of the land species described in the Holy Verse are to be understood from Ahadith. In several Holy Verses (2:168, 5:4, 5:5, 5:88), Allah -azwj Commands believers to eat from ‘the good things’; when interpreting ‘good things’ by opinion, there are going to be countless opinions and disagreements among the believers; thus, one is compelled to turn to the Ahadith for guidance.
Also, Allah -azwj Says: And what reason is there for you that you should not be eating (the meat) from what Allah’s Name has been mentioned upon and He has Detailed for you what is Prohibited unto you, except what you are desperate towards ? And that many are being strayed by their whims without knowledge.
Surely your Lord, He is more Knowing with the exceeders [6:119] The above Verse says that the meat of species, which are prohibited, are explained in detail ; surely, these details are given by Allah -azwj through His Prophet -saww , which we find in the Ahadith. As Allah -azwj Says: He (Prophet) does not speak of his own desire, it is not but a revelation that is revealed (53:3-4) .
[4] Coming back to the permissibility of seafood, we find a difference of opinion among Muslim scholars, whether the meat of snails (terrestrial or aquatic) and scraps can be consumed! [5] [6] [7] [8] Are snails Halal? As these are eaten in several Muslim regions.
Therefore, it is not so straightforward to call all of the seafood permissible based on the interpretation of the above quoted Holy Verse by one’s opinion, but one must review it in more detail to ensure that a believer’s food intake is Halal, so if one is not entirely convinced, it is better to refrain from eating that on which one lacks conviction – a Hadith, see in ref. [9] Similarly, one cannot eat all parts of a slaughtered animal, e.g. sheep.
There is some difference of opinion, but generally, Ahadith forbid the consumption of blood, glands, blood vessels of the heart, spleen, spinal cord, and genitals!
