Allah, the one treue God. The word 'Allah' is the preferred word and name to call God by. Unlike other languages, it doesn't have a masculine, feminine or neuter connotation for He is above that. The term 'He' is used as we as humans have limited capacity to understand the true nature of God (in this life). Interestingly, the word 'Allah' also cannot linguistically have a plural (eg.God(s)); it just doesn't make sense - the beauty of the Arabic language.
