Haram
Alcoholic intoxicants are prohibited in Islam. Khamr is the Arabic word for alcoholic drinks that cause intoxication. The Prophet declared that the prohibition was not only placed on wine, but the prohibition also included beer and other alcoholic beverages that intoxicate a person. The Prophet also forbade the trading of these intoxicants, even with non-Muslims. It is not permissible for a Muslim to import or export alcoholic beverages, or to work in or own a place that sells these intoxicants. Giving intoxicants as a gift is also considered haram.
Halal
The most common example of "haram" (non-halal) food is pork (pig meat products). While pork is the only meat that categorically may not be consumed by Muslims (the Quran forbids it, Sura 2:173 and 16:115 ) other foods not in a state of purity are also considered "haram". The criteria for non-pork items include their source, the cause of the animal's death, and how it was processed. It also depends on the Muslim's "madhab".
Muslims must also ensure that all foods (particularly processed foods), as well as non-food items like cosmetics and pharmaceuticals, are "halal". Frequently, these products contain animal by-products or other ingredients that are not permissible for Muslims to eat or use on their bodies. Foods which are not considered "halal" for Muslims to consume include blood and intoxicants such as alcoholic beverages. A Muslim who would otherwise starve to death is allowed to eat non-"halal" food if there is no "halal" food available.
