Adab (Arabic: أدب) in the context of behavior, refers to prescribed Islamic etiquette: “refinement, good manners, morals, decorum, decency, humaneness”. While interpretation of the scope and particulars of Adab may vary among different cultures, common among these interpretations is regard for personal standing through the observation of certain codes of behavior. To exhibit Adab would be to show “proper discrimination of correct order, behavior, and taste.
Islam has rules of etiquette and an ethical code involving every aspect of life. Muslims refer to Adab as good manners, courtesy, respect, and appropriateness, covering acts such as entering or exiting a washroom, posture when sitting, and cleansing oneself. According to Sahih Bukhari, Muhammad refrained from bad language; neither a ‘Fahish nor a Mutafahish. He used to say “The best amongst you are those who have the best manners and character.”
