Allah - Means "The Only One to be Worshipped"  "Allah" is the same word used by Christian Arabs and Jewish Arabs in their Bible, centuries before Islam came.

On page one [1] of Genesis in the Old Testament, we find the word "Allah" seventeen [17] times.

The Holy Quran says: Surah 112

Say: He is Allah, the One and Only; 

Allah, the Eternal, Absolute; 

He begetteth not, nor is He begotten; 

And there is none like unto Him. 

Allah says in the Quran: 
"Truly, I am Allah; there is no God but I; therefore serve Me"
[Al-Qur’an 20:14]

Things exist by His will

"When We decree a thing, We need only say: 'Be', and it is "
[Al-Qur’an 5:32]

"Surely, your Lord is Allah, Who created the heavens and the earth in six days,

then ascended His Throne, Ordaining all things"
[Al-Qur’an 10:3]
