According to Islam, the present world is not an eternal abode. The Qur'an tells us that man is placed here only temporarily, so that his moral fibre may be tested in terms of his obedience to God's will. He must always remember that there will be the life hereafter, or Akhirat as it is known in Islamic terminology. This is also referred to as Ma'ad, which means a place to which one returns.
There is a time limit to mortal existence. Death marks the end of the testing period for all human beings. But death only means a change of abode, for the soul never dies. Man returns to the realm whence he came, so that he may wait for Judgement Day. That realm, the life hereafter, is the eternal world. Thus man's life is divided into two parts: a brief stay in this world and an eternal life in the next world. To the ungodly, it is only then that it becomes obvious that a life which is eternal is far more important than this present existence.
God created human beings and made them responsible for their actions by granting them freedom. If there were no Afterlife in which the good were rewarded and the bad punished, there would be no justice; in which case, it would appear meaningless to create people with a conscience and a sense of responsibility. But God is just and always acts justly. Hence it is the absolute demand of justice that there should be a Day of Judgement on which everyone is brought to book.
After death, human beings will, therefore, leave this present, ephemeral abode and, on the Day of Judgement, will enter another world, which will be eternal. When the time comes for the Last Reckoning, God will destroy this world and replace it with a permanent, everlasting world. All human beings will then be resurrected and brought before the Almighty to be judged. On that day, everyone will stand alone before God. Those who have done good deeds in the world they have left behind will be rewarded. Their reward will be paradise, a state of joy, happiness and peace.
The Qur'an states: "God has created death and life to test which one of you is best in conduct." (67:1)
Death is not the end of our lives; it is the beginning of our real life. Because our future fate is being decided on the basis of our present performance, we can either make use of our opportunities on earth to ensure a well-deserved place for ourselves in Paradise, or we can throw them away and condemn ourselves to punishment in Hell.
The belief in the Hereafter naturally has a great influence on the life of a believer. When he knows that God is watching all his actions, his behaviour will be responsible. He will always endeavour to lead his life in consonance with the will of God and will inevitably avoid any course which will incur God's displeasure.
Furthermore, the concept of the Hereafter gives a fuller meaning and purpose to the life of the believer. One who firmly believes in this concept will not give in to greed and other such worldly failings. He will not be a materialist, for he knows that this material life will surely come to an end with death, whereas there will be a whole eternity before him in the Afterlife, during which he will certainly rejoice in having paid due attention to the spiritual side of life on this earth.
