‘Allah’ instead of ‘God’?

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.
