Arabic name

Arabic names have historically been based on a long naming system. Many people from Arabic-speaking and also non-Arab Muslim countries have not had given, middle, and family names but rather a chain of names. This system remains in use throughout the Arab and Muslim worlds.

The ism (اسم) is the given name, first name, or personal name; e.g. "Ahmad" or "Fatima". Most Arabic names have meaning as ordinary adjectives and nouns, and are often aspirational of character. For example, Muhammad means 'Praiseworthy' and Ali means 'Exalted' or 'High'.

The syntactic context will generally differentiate the name from the noun or adjective. However, Arabic newspapers will occasionally place names in brackets, or quotation marks, to avoid confusion.

In fact, the name Muhammad is so popular throughout parts of Africa, Arabia, the Middle East, South Asia and Southeast Asia, that it is often represented by the abbreviation "Md.", "Mohd.", "Muhd.", or just "M.". In India, Pakistan, Bangladesh, Malaysia, Indonesia and the Philippines, due to its almost ubiquitous use as a first name, a person will often be referred to by their second name:

The nasab (Arabic: نسب, lit. 'lineage') is a patronymic or matronymic, or a series thereof. It indicates the person's heritage by the word ibn (ابن "son of", colloquially bin) or ibnat ("daughter of", also بنت bint, abbreviated bte.).^{[citation needed]} In the 1995 book Name Studies (De Gruyter), Wolfdietrich Fischer [de] wrote that, although the nasab was still common contemporarily, ibn and bint were omitted "in almost all Arab countries".

Ibn Khaldun (ابن خلدون) means "son of Khaldun". Khaldun is the father's personal name or, in this particular case, the name of a remote male ancestor.

ʿAmmār ibn Sumayya means "ʿAmmār son of Sumayya". Sumayya is the personal name of ʿAmmār's mother, the same person can also be identified by his father's personal name "ʿAmmār ibn Yasir". In later Islamic periods the nasab was an important tool in determining a child's father by means of describing paternity in a social (i.e. to whom was the mother legally married during the conception of the child), not a biological sense, because the father's biological identity can be grounds for speculation. In early Islamic contexts this function is not yet well established. This stems from a legal principle introduced by Islam regarding the legal status of children (they can only arise from marriage) and changes to waiting periods relating to divorce to establish an undisputed legal father for any child. This function only developing with Islam means that one can find many Companions of the Prophet bearing a maternal nasab, as the naming conventions reflected in their names still stem from pre-Islamic attitudes and beliefs.

Several nasab names can follow in a chain to trace a person's ancestry backwards in time, as was important in the tribal society of medieval Arabs, both for purposes of identification and for socio-political interactions. Today, however, ibn or bint is no longer used (unless it is the official naming style in a country, region, etc.: Adnen bin Abdallah). The plural is 'Abnā for males and Banāt for females. However, Banu or Bani is tribal and encompasses both sexes.
