In the Name of Allah, the Most Gracious, the Most Merciful
The word 'Allah' is the combination
of two Arabic words 'AL Ilâh' which means “The God'; it is the proper
name of the only Supreme Being Who exists necessarily by Himself.
This word comprises all the attributes of perfection. This word is neither
feminine nor plural and has never been applied to any other being
This word has no corresponding word in English or in any other language of
the world. Allah is the One and Only True God's personal name. Nothing or
no one else can be called Allah. That is why Muslims use the word Allah, His
personal name, and not God.
It is interesting to note that Allah is also used for God in Aramaic, the language of Jesus, peace be upon him, and that
all Arab Jews and Christians also use the word Allah for God.
