Etiquette and diet

Main articles: Adab (behavior) and Islamic dietary laws

Many practices fall in the category of adab, or Islamic etiquette. This includes greeting others with "as-salamu `alaykum" ("peace be unto you"), saying bismillah ("in the name of God") before meals, and using only the right hand for eating and drinking. Islamic hygienic practices mainly fall into the category of personal cleanliness and health, such as the circumcision of male offspring. Islamic burial rituals include saying the Salat al-Janazah ("funeral prayer") over the bathed and enshrouded dead body, and burying it in a grave. Muslims are restricted in their diet. Prohibited foods include pork products, blood, carrion, and alcohol. All meat must come from a herbivorous animal slaughtered in the name of God by a Muslim, Jew, or Christian, with the exception of game that one has hunted or fished for oneself. Food permissible for Muslims is known as halal food.[66]
