4- Immortality
In the discussion of knowing God, it was proved that the wide world is having the being of God, who is the creator and controller of the creatures. His knowledge, power and wisdom were also proved and also that He never does anything illogical and aimless. But His aim in the creation of the world was not to satisfy any of His needs since He is needless; on the contrary His aim was to benefit and perfect. He bestows perfection to every phenomenon according to its capability. His gracefulness is in His being and miserliness is not present therein. Between the phenomena of the world, man is having an extraordinary and a distinctive position in his capability.
His body is from the material world and his soul is from the spiritual and the celestial world. The material world, throughout years and extremely long centuries, has developed the capacity through perfections of actions and reactions so that it may assume the form of an astounding man. His physical constitution is composed of digestive system, organs of hearing, sight, smell, speech, reproduction, blood circulation and other organs, which operate through astonishing niceties, some of which are mentioned in books of science.
More important than all this is especially the creation of the celestial soul of man; his reasoning power and intelligence; and an extraordinary mechanism of his thinking faculty consisting of his learning ability and memory retention. Man is created in such a way that he is able to remove the curtain from the secrets of the world through contemplation, reasoning and his experience and controls the material world one after another. He inhabits the world and makes it useful for himself and other human beings. Therefore, all the phenomena of the material world, different types of plants and animal, earth, mines, atmosphere, light and elements are practically at the disposal of man and he has the power to control and use them at present or in the future.
In conclusion, we can define man as the by-product of rotation and search of the material world and the pick of the whole lot of the system of creation. Aim of creation of the world should also be searched in him.
Now this important question arises that can we consider that the aim of creation of this world and most important of all, creation of man whose life is at the most a hundred years, which is filled with various types of hardships, calamities and unhappiness is short in comparison to the seeking of pleasures and to say: Death is the end of life of man and his complete annihilation? Your reply is an absolutely negative. If it was so, creation and running of the material world; its coming into existence and life of man would all have been meaningless. An absurd action is not expected from any sane person; how can we expect it from the Almighty Allah, who is all-powerful, all-knowing, wise and needless?
Therefore it can be said that man is created for an everlasting life in the hereafter and not for destruction and annihilation. The aim of the Almighty Allah in creation of man is that he should live in this world and train himself in good manners and good deeds and prepare for an everlasting good life in the hereafter. He created him with this aim, equipped him with ability for perfection programmed for his personal success of the hereafter. He also sent prophets to guide man. In this way, creation of world and man can be justified rationally.
This is indicated in the verses of Quran; as for example:
وَمَا خَلَقْنَا السَّمَآءَ وَالْأَرْضَ وَمَا بَیْنَهُمَا لَاعِبِینَ
And We did not create the heaven and the earth and what is between them for sport. (21:16)
أَفَحَسِبْتُمْ أَنَّمَا خَلَقْنَکُمْ عَبَثاً وَأَنَّکُمْ إِلَیْنَا لَا تُرْجَعُونَ
What! did you then think that We had created you in vain and that you shall not be returned to Us? (23:115)
وَمَا خَلَقْنَا السَّمَوَ تِ وَالْأَرْضَ وَمَا بَیْنَهُمَآ إِلَّا بِالْحَقِّ وَإِنَّ السَّاعَةَ لَأَتِیَةٌ فَاصْفَحِ الصَّفْحَ الْجَمِیلَ
And We did not create the heavens and the earth and what is between them two but in truth; and the hour is most surely coming… (15:85)
