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.
Caffeine
Caffeinated beverages are widely consumed by Muslims today. In the 16th century, some Muslim authorities made unsuccessful attempts to ban them as forbidden "intoxicating beverages" under Islamic dietary laws.
