It is sometimes difficult to separate concepts in Islam from concepts specific to Arab culture, from the language itself. The Qur'an is expressed in Arabic and traditionally Muslims deemed it untranslatable, though this view has changed somewhat in recent decades. Concepts that derive from both Islam and Arab tradition, which are expressed as words in the Arabic language, and are sufficiently specific to these to require their own articles here, are:

NOTE: Wikipedia is not a general Arabic-to-English dictionary. The list above includes only those concepts sufficiently specific to Islam or Muslim culture to merit their own full articles. The prime purposes of this list are to disambiguate multiple spellings, make note of spellings no longer in use for these concepts, define the concept in one line to make it easy to pin down the one you're looking for, and provide a guide to unique concepts of Islam all in one place.

There is an English/Arabic dictionary on wiktionary.

Other notes:

The English word algorithm is derived from the name of the inventor of algebra - an Arabic word like alchemy, alcohol, azimuth, nadir, zenith and oasis, which mean the same as in English.

Arabic numerals are what we use in English ("0", "1", "2",...). The modern Arabs in Arabia generally use the Hindi numerals.

Some English words or phrases would translate very poorly into Arabic for cultural reasons, for instance the English word "crusade" would most likely be interpreted as meaning "genocide", and "infinite justice" would most likely be interpreted as meaning "divine judgement" - adl in Arabic implying Allah's justice. Probably it is best to avoid such terms for anything one intends to translate into Arabic, or knows will be translated.

Some Islamic concepts are usually referred to in Persian or Turkic. Those are typically of later origin that the concepts listed here - for completeness it may be best to list Persian terms and those unique to Shia on their own page, likewise Turkic terms and those unique to the Ottoman period on their own page, as these are culturally very distinct.
