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 himself. Therefore it is his duty to know his master, the Creator.
Man is a unique creature.
God gave man the ability 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. Man is born pure and sinless and is given the choice to do righteous deeds or indulge in sins. 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.
