Many matters of etiquette in the Middle East are connected to Islam as it is written in the Qur'an and how it has been traditionally understood and practiced throughout the centuries. Prescribed Islamic etiquette is referred to as Adab, and described as "refinement, good manners, morals, ethics, decorum, decency, humaneness and righteousness". As such, many points discussed in this article are applicable in other regions of the Islamic world. This holds especially true in Muslim majority countries outside Middle East.
