Man stands at the peak of creation and holds the position of the master in this universe owing to the unique qualities he enjoys. He is provided with a number of faculties and qualities that enable him to control and build this world. He is endowed with sense to make him understand things and acquire knowledge. He is also provided with the means of power and control. He enjoys, a variety of emotions and feelings, such as love, hate, anger, etc.
These qualities are two-edged weapons that can be employed either for good or for evil purposes. Power for example, can be used either for helping people and giving them happiness or misleading the weak and oppressing them. The human mind can be used either for inventing the means of luxury and comfort or for manufacturing the devices of death and destruction.
Therefore, there must be some other force or drive that can control these human qualities and faculties and direct them in the interest of man and his community. That is, the sound belief in the One and Only true God and His perfect attributes and in the resurrection after death when everybody is brought to account for his past deeds. This belief will be the main factor that leads man in the right path and keeps him away from evil and injustice. It helps to build a real ideal society as it was witnessed in the past when Islam was embodied in actual life and the Muslim society was a concrete representation of the Islamic faith.
In fact, Allah does not need our belief in Him, nor does He need our worship and submission to His exalted Will; it is we who need this belief in order to be correct in our concept of life, the Universe and its Creator, and to achieve our happiness and welfare both in this world and in the Hereafter.
