Man is the greatest creature on the face of the earth. He is the intellectual being who can subject all other beings to serve him. The greatest thing in this man is his mind by which he reached the moon, dove into the depths of the oceans, and achieved the scientific miracles.
Today, we enjoy these achievements as man managed to communicate with the whole world instantly in voice and image. Despite these numerous and great achievements, wars, tragedies, suffering, pains, and diseases are still increasing in all corners of the world; we have not been able to put an end to them yet, let alone the fact that we most of the times are the cause of them.
If man, who made the computer in a stimulation of the human mind, has reached the latest operating systems of this computer, so what is the most efficient human operating system that can repair man and be suitable for him?
And also in your own selves; can you not see? (Quran 51:21)
