1) I wanted to ask you; Is Allah the name of God Almighty? Or is it a word that means God Almighty?

2) Is it the meaning of the word Allah which means God that is His name or is it the letters alif lam lam ha that is his name?

1) Allah is one of the names of God and it literally means God- which applies only to God. It is a name that no one else can name because it is the description and the name of God at the same time.

2) اله is God; ال before it is a title for the only God
So it is الله
