The submission of man to His Creator is the essence of Islam. The name "Islam" is chosen by God (Allah) and not by man. It is the same unifying Message revealed to all the Prophets and Messengers by Allah, and which they spread amongst their respective nations. It was revealed in its final form to Muhammad, sallallaahu ‘alayhi wa sallam, (may Allah exalt his mention) as a complete Message to humanity.
The Lord, Allah, is the True and Only Creator that deserves to be worshipped. No worship is worthy of being given to a stone, statue, a cross, a triangle, Krishna, Guru, Buddha, Mahatma, sun, moon (not even to the namesake from Korea!), light, fire, rivers, cows, Rama, temples, saints, priests, monks…all these are created beings or things.
Allah is the Name of The One True God. His Name is not chosen by man and does not have a number or gender. It is known that Allah is the Name of God in Aramaic, the language of our beloved Prophet 'Eesaa (Jesus), may Allah exalt his mention, and a sister language of Arabic. The Name "Allah" has been used by all previous Prophets starting with Aadam (Adam), may Allah exalt his mention, and by the last and final Prophet Muhammad, sallallaahu `alayhi wa sallam ( may Allah exalt his mention ).
The innate nature in man recognizes what is good and bad, what is true and false. It recognizes that the Attributes of Allah must be True, Unique, and All Perfect. It does not feel comfortable with any kind of degradation of His Attributes. Many who became "discontent with God" did so because of the practices of the Church in medieval Europe, and because of the claims of "god dwelling in a son" and the concept of "original sin".
