How is Halal Meat Slaughtered? As you know that Islam defines what is halal and Haram (Prohibited) meat to eat, in the same way Islam also define how Halal Animal is slaughtered, or what is the Islamic method of slaughtering the Animal.

Slaughtering in Islamic terminology is said to be Dhabiḥah or Zabiha, an Arabic word, (ذَبِيْحَة) is the prescribed method of slaughtering all meat sources, excluding fish and other sea-life, per Islamic law. As Allah says in Quran;
 

"Forbidden to you (for food) are: dead meat (Arabic: maytatu), blood (Arabic: damu), the flesh of swine (Arabic: walahmu-lkhanziri) and that on which has been invoked the name of other than God that which has been killed by strangling or by a violent blow (Arabic: mawqudhatu) or by a headlong fall or by being gored to death; that which has been (partly) eaten by a wild animal; unless you are able to slaughter it”

This method of slaughtering halal animals consists of using a well-sharpened knife to make a swift, deep incision that cuts the front of the throat, the carotid artery, windpipe, and jugular veins. It is preffered that the head of an animal that is slaughtered using halal methods is aligned with the qiblah (The direction of Kaba).

In addition to the direction, permitted animals should be slaughtered upon utterance of the Islamic prayer "in the name of God." Because it is the verse of the Quran to name Allah when having any eating thing, and naming other than Allah SWT is considered to be Shirk i.e. associating partners with Him according to the Islamic dietary laws. Allah says in Quran,
 

“They ask you what is lawful to them Say: lawful to you are (all) things good and pure: and what you have taught your trained hunting dogs in the manner directed to you by God: eat what they catch for you, but pronounce the name of God over it”

Moreover, it is preferred in Islam that the animal slaughtered must be killed quickly with a sharpened blade. It must not suffer. It must not see the blade. It must not see or smell the blood from a previous slaughter. All this is permissible and most recommended, however, not included in basic rulings of slaughtering the animal in Islam.

As there exist halal ways for meat to be slaughter, there are ways which are strictly prohibited of killing the halal animal, such as boiled or electrocuted, and the carcass should be hung upside down for long enough to be free of blood. In addition, the rulings of slaughtering in Islam doesn’t apply on sea food, all water game is considered halal (although the Hanafi madhhab differs on this) as stated in Quran,
 

"Lawful to you is game from the sea and its food as provision for you [who are settled] as well as for travellers, although you are forbidden to hunt on land while you are in the state of pilgrimage. And be conscious of God, unto whom you shall be gathered." (Qurʼan 5:96.)
