Those who have a brief idea about the laws of nature know that all creations in this world are ruled by a certain law. This law is so balanced that the intellectuals and scientists can compile their books on the basis of these great regulations e.g. the space program and even the journey to different planets are arranged on the basis of these formulas.
In short, we will find the system of justice that covers everything wherever we look. From the great links of the solar systems to minute atoms,
On the other side man cannot be above this law that the creator has imposed on the whole of the universe because in that condition man will be the odd one out. So this idea of being above the law is very illogical and without proof. We are sure that such a court of justice has been instituted for mankind also where all will be presented to be judged.
The Ulema of religious belief have been taking the benefit of this proof about resurrection. They spoke about the oppression because of which justice was not implemented and about the tyrants who had the best of life. They also spoke about the oppressed who were subjected to oppression till the last breath of their lives.
Is the Just God agreeable to this? Are not such scenes contrary to His justice?
So the learned scholars discerned that there should be another world where the justice of God will be fully implemented. Rewards will be given to every one who has done even a little good and punishment to those who have done even a little sin or mischief.
So the Day of Judgment is the sign of God’s justice and the answer to all the doubts and questions.
