Islamic dietary laws are laws that Muslims follow in their diet. Islamic jurisprudence specifies which foods are ALA (حَلَال, "lawful") and which are ALA (حَرَامْ, "unlawful"). The dietary laws are found in the Quran, the holy book of Islam, as well as in collections of traditions attributed to Islamic prophet Muhammad ("Sunnah").
Herbivores, cud-chewing animals like cattle, deer, sheep, goats, and antelope are some examples of animals that are halal only if they are treated like sentient beings and slaughtered painlessly while reciting the Bismillah and Takbir. If the animal is treated poorly or tortured while being slaughtered, the meat is haram. Forbidden food substances include alcohol, pork, carrion, the meat of carnivores, and animals that died due to illness, injury, stunning, poisoning, or slaughtering not in the name of God.
Quranic verses which have information regarding halal foods include: Q2:173, Q5:5, and Q6:118–119, 121.
Livestock or cattle, i.e. grazing beasts, are lawful except those that are explicitly prohibited. However, hunting is prohibited during "the pilgrimage" (Quran 5:1).
This means that most herbivores or cud-chewing animals like cattle, deer, sheep, goats, and antelope are considered halal to consume.
Animals hunted by trained birds and animals are also permitted according to the Quran 5:4.
Dhabīḥah
In Islamic law, ALA-LC (ذَبِيحَة) is the prescribed method of slaughter for halal animals. It consists of a swift, deep incision to the throat with a very sharp knife, cutting the wind pipe, jugular veins and carotid arteries on both sides but leaving the spinal cord intact.
The carcass should be hung upside down for long enough to be free of blood.
Slaughtered animals must be acknowledged as sentient beings and slaughtered painlessly while reciting the Bismillah and Takbir. The butcher is required to call upon the name of Allah (Bismillah) individually for each animal. If the animal is treated poorly, or tortured while being slaughtered, the meat is haram.
