The word "A'La" (transliterated as "al-'Ala") means "the Most High" or "the Exalted." When used with Allah, it forms the name "Allah al-'Ala," which means "Allah, the Most High" or "Allah, the Exalted." The word "Ilah" (transliterated as "ilah") means "god" or "deity." When used with Allah, it forms the name "Ilah Al.
Etymologically, the name Allah is probably a contraction of the Arabic al-Ilh, the God. The name's origin can be traced to the earliest Semitic writings in which the word for god was il, el, or eloah, the latter two used in the Hebrew Bible (Old Testament).
