Non-believers are unable to provide any convincing reason for the existence of this universe or of human life. People who believe there is a Creator assume that creation occurred by His will. But in a world where everything is shown to have a purpose, it is natural for a human
being to wonder about the purpose of his own creation. One is surely justified in expecting the Creator who put us on this earth to inform us why He did so and what He expects of us.
The Qur'an informs us that He did just that. It says God created us for a test here on earth, conveying His words:
"Then did you think that We created you uselessly and that to Us you would not be returned?"[23:115-116]
A non-believer might decide that the objective of his life will be to collect wealth, obtain position or pursue pleasure to the greatest extent possible. But none of this will benefit him in the long run. According to His final scripture, God created man to test him with certain responsibilities [As stated in 18:7, 67:2 and 76:2]. He did not intend life on this earth to necessarily be comfortable or satisfying but merely a trial of limited duration, the punishment and rewards of which will be due in the Hereafter.
