The method of killing a goat for the Eid is as follows:
The method of slaughtering an animal is that the four main arteries of its neck should be completely cut (jugular artery, foodpipe, jugular vein and windpipe). It is not sufficient to split open these arteries or to cut off the neck. And the cutting of these four main arteries becomes practical when the cutting takes place from below the knot of the throat.
If a person cuts some of the four arteries and waits till the animal dies and then cuts the remaining arteries, it will be of no use. If the four arteries are cut before the animal dies, but the cutting was not continuous as is usually done, the animal is Pak and halal to eat. However, the recommended precaution is that they should be cut in continuous succession.
A person, a man or a woman, who slaughters an animal must be a Muslim. An animal can also be slaughtered by a Muslim child who is mature enough to distinguish between good and bad.
The animal should be slaughtered with a weapon made of iron. However, if an implement made of iron is not available, it should be slaughtered with a sharp object like glass or stone, so that the four veins are severed, even if the slaughtering may not be necessary, like when the animal is on the verge of death.
When an animal is slaughtered, it should be facing Qibla. If the animal is sitting or standing, then facing Qibla would be like a man standing towards Qibla while praying. And if it is lying on its right or left side, then its neck and stomach should be facing Qibla. It is not necessary that its legs, hands and face be towards Qibla. If a person who knows the rule, purposely ignores placing the animal towards Qibla, the animal would become haraam; but if he forgets or does not know the rule, or makes a mistake in ascertaining the Qibla, or does not know the direction of Qibla, or is unable to turn the animal towards Qibla, there is no objection. As a recommended precaution, the person slaughtering should also face Qibla.
When a person wants to slaughter an animal, just as he makes the Niyyat to slaughter, he should utter the name of Allah, and it suffices if he says 'Bismillah' only, or if he utters 'Allah'. But if he utters the name of Allah without the intention of slaughtering the animal, the slaughtered animal does not become Pak and it is also haraam to eat its meat. And if he did not utter the name of Allah forgetfully, there is no objection.
It is necessary that the blood should flow in normal quantity from the slaughtered animal. If someone blocks the vein, not allowing blood to flow out, or if the bleeding is less than normal, that animal will not be halal. But if the blood which flows is less because the animal bled profusely before the slaughter, there is no objection.
The animal should be slaughtered from its proper place of slaughtering; on the basis of recommended precaution, the neck should be cut from its front, and the knife should be used from the back of the neck.As a precaution, it is not permissible to sever the head of the animal from its body before it has died, though this would not make the animal haraam. But if the head gets severed because of sharpness of the knife, or not being attentive, there is no objection. Similarly, it is not permissible to slit open the neck and cut the spinal cord before the animal has died.
