Halal animals (permitted animals) may be hunted with sharp weapon, like arrow etc, or a trained hunting beast, provided it is left saying Bismillah (in the name of Allah) such hunted animal can be eaten without slaughtering (Zubah). If Bismillah is not uttered or other animals untrained joined the trained animal or the trained animal eats after hunting or the sharp part of the weapon does not strike the animal, it is not permissible for eating.
Eating the following parts of the slaughter (Zubah) animal is strictly undesirable (Makrooh-e-Tahreemy)
1. Gallbladder, glands, testicles, penis, spinal cord (Haram Maghz). (Durre Mukhtar and Sirajul Wahhaj)
The flowing blood is prohibited through Quranic verses.
The Following Animals are Prohibited (Haram) for Eating
Beasts with curved teeth, birds catching their prey with paws, insects i.e. snake, scorpion, musk, rat, ants, white nats, earthworm, lizard, chameleon, etc. and the local crow that eats dead, domestic ass, mules, pigs, badger, wasp, tortoise, vulture, mongoose and elephant etc. (Ahsanul Masail)
Allah says:-
(S2-A173) "Except those things that have been prohibited to you, the dead meat
and blood and the pork or that which is sacrificed in the name of other (dieties). But one
who is helpless and not going beyond the limits nor his bounds for him it is not a sin.
Indeed Allah is kind and forgiving."
Important. For one who is desperate and about to die of hunger a prohibited thing becomes permissible. According to Imam Azam Rah. such person is bound to eat it to save his life. If he dies of hunger he will be a sinner. But he should eat just to save his life and not to the full satisfaction. (Mala Budh Minho)
Important. Among water animals without slaughter (Zubha) only fish is permissible for eating. But the fish which has died in the water and floating is prohibited. Except fish no other water animal is permitted (Halal) (Ahsanul Masail)
If a permitted animal falls from the height and dies, or dies of the suffocation or is slaughtered by a non believer or at the time of slaughter intentionally it was omitted to utter Bismillah, then it is prohibited (Haram)
Allah Says:-
(S5-A4) Dead animals are prohibited for you and blood (That flows) and the pork and
the animals that are nominated on other than Allah’s name or which is killed by
suffocation and
which dies by falling from a height, which is killed with a stroke of stick or club or
dies when
attacked with horns. And which is killed and being eaten by a wild animal.
The peacock and the parrot are permissible for eating. (Alamgiri)
Wild crow which eats grains in the fields and does not eat dirty things and wild donkey i.e. wild ass is permissible (Halal). (Ahsanul Masail)
Camel, cow, ox, goat, deer, etc. animals eating grass, leaves etc., are permissible (Halal). Allah says:-
(S5-A1) "Permitted are the four footed (Grazing) animals.
Important: If a Hindu, polythiest or fire worshipper etc. sells meat and says that he has got the animal slaughtered by a Muslim. in this case, his assertion cannot be taken for granted. It is not permissible to purchase and eat the flesh. If he gets the animal slaughtered by a Muslim in the presence and sends its flesh through his daughter or daughter-in-law or another polythiest to the house of the Muslim, taking and eating of this flesh is not permissible (Not Halal)
After slaughter (Zubah) if the flesh disappears from sight even for a moment, then buying it from an infidel and eating it is not permissible. But if it does not disappear from the sight, then its buying and eating is permissible.
NOTE:- A verdict (Fatwah) is given in Mala Budh, published in 1318 Hijra in this regard.
