If it is supposed that there is no concept of eternal reward and punishment then it implies that those great people who devoted their lives for some noble cause and faced impediments in the way and those who embarrassed martyrdom in the pursuit of their goals have wasted their lives. But this is something that is completely illogical and irrational, which cannot be accepted by a normal human mind. So the faith in resurrection is imperative for the welfare of humanity
The belief in Resurrection implies that each and every object of the world has to vanish on a fixed moment prescribed by the Allah Almighty, i.e. on doomsday. An angel, namely Hazrat Israfeel has been assigned a special responsibility in this regard by the Allah Almighty. On Doomsday he would blow trumpet that would bring to an end the process of life on earth and all the living beings would die instantly. After a prescribed time, he would again blow the trumpet at the command of Allah Almighty that would give another eternal life to the human beings for thorough and foolproof accountability. All the human beings would be gathered by the Allah Almighty and they would be rewarded and punished as per their deeds in this worldly mortal life. There would be no fragment of injustice on that
This whole process has been summarised and elaborated by the Allah Almighty in Surah Al-Qaria/Chapter the Calamity when He says :-
What is the Calamity?
And what do you know what the Calamity is?
On that Day human beings shall be like scattered moths,
and the mountains shall be like fluffs of carded wool in varying colours.
Then he whose scales weigh heavier (whose good deeds are more than bad deeds)
shall have a blissful life;
but he whose scales weigh lighter,
his shall be the deep pit for a dwelling.
And what do you know what that is?
A blazing fire!
‘Tell them: The death from which you flee will certainly overtake you. Then you will be returned to Him Who fully knows what is hidden and what is manifest. Thereupon He will let you know all that you used to do.
So this is a crystal clear sign for those who think and it should make us realise that this life is not a lasting one. Furthermore, the teachings of Islam tells us that the taste of death is not some thing pleasant and especially it is a dreadful forced end for those who lead a sinful life. That’s why the Holy Prophet (PBUH) stated,
‘If the animals had been so conversant with the knowledge of death as the human beings, no fat animal would have been available for eating.’
He further stated,
‘I am leaving among you two preachers’first the quiet preacher, i.e. death and the second the talking preacher, i.e. the Holy Quran.’
The belief in resurrection is imperative for perfect justice as human beings cannot disseminate perfect and comprehensive justice owing to the limited nature of this worldly life. For example, if a person kills one hundred persons, we cannot kill him/her one hundred times. Similarly, if it is supposed that there is no concept of eternal reward and punishment then it implies that those great people who devoted their lives for some noble cause and faced impediments in the way and those who embarrassed martyrdom in the pursuit of their goals have wasted their lives. But this is something that is completely illogical and irrational, which cannot be accepted by a normal human mind. So the faith in resurrection is imperative for the welfare of humanity.
Sleep also reminds us about the hereafter. During sleep, we remain cut off from worldly life and some time we experience immense pleasure or severe pain or tragic grief in dreams. But when we get up we find an entirely different life. So this common practice of human life is another proof of hereafter that is very easy to understand.
The belief in Resurrection has enduring and lasting effects on the human society and goes a long way in its reformation. This belief creates a sense of responsibility among the human beings. Through this belief the human beings get rid of despair and frustration because the hope of eternal reward enables them to face worldly problems with grace and courage, which in turn makes them patient, steadfast and brave who are always ready to sacrifice their bodily and other worldly pleasures for the sake of triumph in the life to come. They prefer the lasting life of hereafter on this mortal worldly life. This belief creates piety and spirituality in the human beings. This belief curtails the fear of death and the tendency of hot pursuit of desires among the believers.
