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 human being is aware that their existence is dependent upon a Creator. He knows for sure that he cannot create himself. Therefore, it is his duty to know his Master, the Creator.
Man is a unique creature. Allaah, the Most Exalted, established 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 has been given the freedom to choose for himself a way of life worthy of his position as Allaah's representative, or to fall lower than the lowest of all animals or creations. Almighty Allaah Says in the Noble Quran (what means):
The Creator, out of His abundant Love and Mercy for mankind has not left us in darkness to discover the right path by trial and error alone. Coupled with our intellectual capability to reason, our Creator bestowed upon us Divine Guidance that outlines the Criterion for Truth, knowledge, as well as the reality of our existence in this world and the Hereafter.
From the beginning of mankind, our Creator sent Prophets, may Allaah exalt their mention, 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 has been conveyed to man in successive generations through the different prophets, may Allaah exalt their mention, who invited mankind to the same Path. However, all the earlier messages or revelations from Allaah Almighty were distorted by people of later generations.
As a result, the pure Revelation from our Creator was corrupted with myths, superstitions, idol worship and irrational philosophical ideologies. The religion of Allaah, the Exalted, in a sense was lost in a plethora of religions. Human history is a testament of man's drift between light and darkness, but Allaah, out of His Abundant Love for mankind, has not forsaken us.
When mankind was in the depths of the Dark Ages, our Creator sent His final Messenger, Prophet Mohammed to redeem humanity with the final Revelation, which represents the ultimate and permanent source of guidance for the whole world.
