Glossary of Islam


The following list consists of notable concepts that are derived from both Islamic and Arab tradition, which are expressed as words in Arabic or Persian language. The main purpose of this list is to disambiguate multiple spellings, to make note of spellings no longer in use for these concepts, to define the concept in one or two lines, to make it easy for one to find and pin down specific concepts, and to provide a guide to unique concepts of Islam all in one place.
Separating concepts in Islam from concepts specific to Arab culture, or from the language itself, can be difficult. Many Arabic concepts have an Arabic secular meaning as well as an Islamic meaning. One example is the concept of dawah. Arabic, like all languages, contains words whose meanings differ across various contexts.
Arabic is written in its own alphabet, with letters, symbols, and orthographic conventions that do not have exact equivalents in the Latin alphabet. The following list contains transliterations of Arabic terms and phrases; variations exist, e.g. din instead of deen and aqidah instead of aqeedah. Most items in the list also contain their actual Arabic spelling.
