Islamic dietary laws

Islamic dietary laws is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Islamic dietary laws rather than just read about it. In short: Islamic dietary laws are laws that Muslims follow in their diet. Islamic jurisprudence specifies which foods are halal (Arabic: حَلَال, romanized: ḥalāl, lit. 'lawful') and which are haram (Arabic: حَرَام, romanized: ḥarām, lit. 'unlawful').

Key takeaways

  • Islamic dietary laws belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Islamic dietary laws to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Islamic dietary laws from memory before moving on to harder problems.

Reference excerpt

Islamic dietary laws are laws that Muslims follow in their diet. Islamic jurisprudence specifies which foods are halal (Arabic: حَلَال, romanized: ḥalāl, lit. 'lawful') and which are haram (Arabic: حَرَام, romanized: ḥarām, lit. 'unlawful'). The dietary laws are found in the Quran, the holy book of Islam, as well as in collections of traditions attributed to the Islamic prophet Muhammad. 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 basmala and takbir. If the animal is treated poorly or tortured while being slaughtered, the meat is haram. Forbidden food substances include alcohol, pork, frog, carrion, and animals that died due to illness, injury, stunning, poisoning, or slaughtering not in the name of God.

Quranic foundation The Quran, which is the divine source, along with the life and teachings of Muhammad (sunnah), explicitly state foods that are prohibited (haram) and permissible (halal). These rules of living are believed as essentials for religious observances, practical life, and the health and well-being.

Etymology The Arabic word halal literally translates to 'lawful' or 'permitted'. In Sharia law, this refers to what is lawful by Allah. The word haram translates to prohibited and one who breaks this are considered sinful.

Rules Based on Islamic scriptural injunctions, Islamic dietary laws are classified as halāl (permissible), harām (forbidden), and mashbūh (dubious).

Halal Livestock or cattle, i.e., grazing beasts, are lawful except those that are explicitly prohibited. Hunting is prohibited during "the pilgrimage". Islamic jurisprudence states that all things are essentially halal unless Sharia law states otherwise. The Quran explicitly states numerous halal food items:

Cattle (sheep, goats, camels, buffaloes) Land-hunted animals Meat of animals slaughtered by People of the Book Dates, olives, pomegranates, grapes, and various fruits Animals slaughtered in the name of Allah Cattle's milk and honey Grains Marine hunting (seafood)

Seafood

Seafood is generally permitted in most of the schools of Islam, based on their interpretation of the Quran 5:96; the Hanafi school of Islamic jurisprudence forbids consumption of seafood other than true "fish", and considers other sea creatures, such as crustaceans, to be makruh. Some Hanafi scholars are in disagreement over whether or not prawns and shrimp constitute as true "fish"; comparatively, many scholars do agree that crocodile, crab, lobster, or any mollusk is not.

Mushbooh Foods whose halal status is uncertain or debated may be classified as mushbooh (Arabic: مشبوه; 'doubtful'). This includes foods that are seemingly halal but of an unknown source and ingredients for which the halal status is subject to differing interpretation, such as extract from brewer's yeast, which is nonalcoholic but derived from the production of alcohol.

Ritual slaughter

In Islamic law, dhabīḥah (Arabic: 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 Basmala 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.

Conversely, animals slaughtered for food may not be killed by being boiled or electrocuted. Animals strangled or beaten to death, or that died by falling or due to a wild animal are also expressly forbidden.

Haram A variety of substances are also considered unlawful (haram) for humans to consume and therefore, the consumption of them is forbidden by the Sharia (Islamic law). Haram is typically classified as Haram li-dhatih (textual haram) and Haram li-ghayrih (derivative rules). Textual haram are things explicitly declared in scriptures. Derivative rules are not explicitly stated but prohibited based on Sharia rules and regulations. The Quran states 13 items that are haram:

Dead animals (carrion) – animals must die per Islamic slaughter. Blood – specifically refers to flowing blood, however, the liver, spleen, and the blood remaining in meat or veins after slaughter are permitted. Pork – all parts of a pig are prohibited. Animals slaughtered in the name other than Allah. Strangulated animals Animals killed by injury Fallen dead animals Animals that die from another animal's horn Animals killed by another animal Animals slaughtered at the altar of idols Wine and intoxicating substances Animals incorrectly slaughtered Hunting in Ihram Differences of opinion exist as to whether the consumption of horses, mules, and donkeys is permitted. In the Quran, one finds this verse: "And (He has created) horses, mules, and donkeys, for you to ride and use for show; and He has created (other) things of which you have no knowledge". Some scholars have interpreted this as limiting the named animals for riding and show only, prohibiting their consumption. Predatory animals, such as lions, tigers, falcons and hawks are forbidden as well.

However, a person would not be considered guilty of sin in a situation where the lack of any alternative creates an undesired necessity to consume that which is otherwise unlawful, such as a famine.

Islamic dietary laws during Ramadan

During Ramadan, the ninth month on the Muslim calendar and considered the holy month of fasting, Muslims take time for introspection, prayer, and reading of the Quran. During this period, Muslims focus on self restraint or sawm (Arabic: to refrain), which is one of the five pillars of Islam. During Ramadan, between dawn and dusk, worshippers abstain from food, drink, sexual activity, and immoral behavior. After dusk, Muslims break their fast during a meal called iftar with family and friends. Sawm can be negated by breaking fast, however, the lost can be made up with one extra day of fasting. The end of the Ramadan fast is the celebration of Eid-al-Fitr (Feast of Fast-Breaking), one of the two major religious holidays on the Muslim calendar.

Worked examples

Example 1 — a first encounter with Islamic dietary laws

Start with the simplest possible case. Write down what Islamic dietary laws claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Islamic dietary laws before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Islamic dietary laws ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Islamic dietary laws

In research
Islamic dietary laws appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Islamic dietary laws in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Islamic dietary laws is common in secondary-school and first-year university syllabi. It links to neighbouring topics Diets, Food law, Halal food, so understanding it makes those chapters shorter.
In everyday life
Look for Islamic dietary laws outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
