Hunting of fish
2624. If a fish with scales is caught alive from water, and it dies thereafter, it is Pak and it is Halal to eat it. And if it dies in the water, it is Pak, but it is Haraam to eat it. However, if a fisherman places a net in the water to catch the fish, and the fish dies in the net of the fisherman, while it is in the water, it is most likely Halal, although it is recommended to be avoided from eating. A fish which has no scales is Haraam even if it is brought alive from water and dies out of water.
2625. If a fish falls out of water or a wave throws it out, or the water recedes and the fish remains on dry ground, if someone catches it with his hand or by some other means before it dies, it will be Halal to eat it after it dies.
2626. It is not necessary that a person catching a fish should be a Muslim or should utter the name of Allah while catching it.
2627. If a dead fish about which it is not known whether it was caught from water alive or dead, is bought of a Muslim, it is Halal, but if it is bought of a non-Muslim it is Haraam even if he claims that he has brought it alive from the water; except when a man is certain that the fish was brought alive from the water or two just people confirm his claim.
2628. As per precautionary measures, one should avoid eating a live fish, even though it is most likely Halal to eat a live fish after it is being caught.
2629. If a fish is roasted alive, or is killed out of water before it died itself, as per precautionary measures, it is better to avoid eating it, even though it is most likely Halal.
2630. If a fish is cut into two parts out of water, and one part of it falls into water while it is alive, as per obligatory precaution, one should refrain from eating the part which has remained out of water.
