The Definition of Islam for An Atheist ?

The lexical meaning of Islam is submission, and adherence to the commands of Allah without objection. This is the true essence of Islam. By obeying Allah and observing His commands, the Muslim would be in harmony with the universe in which he lives, for everything in this universe abides by the commands of Allah.

It is an established fact that everything in this universe follows certain rule, and an unalterable law to which it submits; the sun, the moon, the stars, the night, the day, the land, the trees, and the beasts; all submit to a rule which Allah, the Creator, has designated for all these things. Even man himself, when you consider his physical construction, and biological compounds, his need for water and nutrition, heat, air, light, rest, or sleep you would find him submitting to a law under which he has no choice, just like other creatures.

WHAT IS LIFE?

 Man's existence in this world and the creation of this entire universe are not mere accidents or products of a fortuitous nature. This universe, every single atom of it, manifests and leads us to the realization of a Loving, Merciful and All-powerful Creator. Without a Creator, nothing can exist. Every single soul knows that he is existing and that his existence is dependent upon a Creator he knows for sure that he cannot create him self. Therefore it is his duty to know his master, the Creator.

MANKIND

Man is a unique creature. God establishes man as His representative or deputy to govern over all other creatures in this world. He is endowed with the faculty of REASON, which sets him apart from all other animals. Together with this faculty to discriminate and discern, man is given the freedom (free-will) to choose for himself a way of life worthy of his position as God's representative or to fall lower than the lowest of all animals or creations. Man is born pure and sinless and is given the choice to do righteous deeds or indulge in sins.

REVELATIONS

From the beginning of mankind, our Creator sent prophets to convey His REVELATION and to invite human beings to the path of true PEACE and OBEDIENCE to the ONE TRUE GOD. 

This is ISLAM. This message is conveyed towards successive generations of man through the different prophets, all inviting mankind to the same path. However all the earlier messages or revelations from God were distorted by people of later generations. 

As a result, pure Revelation from our Creator was adulterated and polluted with myths, superstitions, idol worship and irrational philosophical ideologies. The religion of God in a sense was lost in a plethora of religions. Human history is a testament of man's drift between light and darkness, but God out of His Abundant Love for mankind has not forsaken us. Islam is not a new religion. It is, in essence, the same message and guidance which Allah revealed to all His prophets, like Adam, Enoch, Noah, Abraham, Ishmael, Isaac, David, Moses, Jesus and Mohammad (Peace Be Upon Them). But the message that was revealed to prophet Mohammad (Peace Be Upon Him) is Islam in its comprehensive, complete and final form.

Say ye: "We believe in Allah, and the revelation given to us, and to Abraham, Isma'il, Isaac, Jacob, and the Tribes, and that given to Mose
