How do u formulate a definite definition of god...

Concept of God varies in different religions. A dictionary def: The supernatural being conceived as the perfect and omnipotent and omniscient originator and ruler of the universe; the object of worship in monotheistic religions. For me it's different a bit, I'm not formulating anything, God already explained about him in his Holy Book. Allah is one, he is self sufficient, neither begets, nor begotten, none comparable unto him. None has the right to to be worshiped but Allah, He is Everliving sustains and protect all things, to him belong all in the heavens and earth, he is Most high, most great, omnipotent, all-knower, all-hearer, merciful, etc.
