The final hour and the eternal life that follows are the most important realities awaiting people. For this reason, this book has stressed the impermanence of this life. Nothing on Earth, not your career, marriage, wealth, or property, is important enough to waste your eternal life pursuing. The only thing worth pursuing and living for is Allah's good pleasure. Allah will begin the eternal life in the most spectacular way. Everyone who meets this Day will realize that this temporary life has definitely come to an end, and will comprehend the Hereafter's existence with certainty.
Before they meet this Day, every person has to remember the hour of the Day of Judgment and what it brings, even though they may never have contemplated it.
The contents of this book have been designed to help you extract yourself from your everyday occupations and desires for a while so that you can see the true purpose for your life. It seeks to inform you in advance about the Day of Judgment that you will most certainly encounter. This is an important warning, because everybody who ignores this Day and its aftermath will witness unbearable events on the Day of Judgment and experience endless hardship in the Hereafter.
You will most certainly encounter this Day, which the Qur'an describes in great detail. You will see that all of your possessions, even your body, will desert you. And then you will be created anew. You must use the opportunity given to you by Allah to obtain the reward, happiness, and peace awaiting you in the Hereafter, which cannot be compared to anything on Earth. The only thing that you have to do is to believe in Allah and the certainty of the Hereafter and be thankful for all the blessings that He gives to you. If you do not, you will experience all-pervasive regret in the Hereafter, for Allah states that:
Those who deny the meeting with Allah have lost, so that, when the Hour comes upon them suddenly, they will exclaim: "Alas for what we neglected there!" They will bear their burdens on their backs. How evil is what they bear! (Surat an-An'am, 31)
This is why you should accept that the Hereafter is a certainty and so prepare accordingly. Only then will your actions during this life have a lasting value, and will you receive an unequalled beautiful return on Earth as well as in the Hereafter. This reward will be the hospitality of Paradise, where you can have everything that you desire. Remember that on the Day of Judgment everybody will be judged alone in Allah's presence. Therefore, make the right efforts and prepare for death and its aftermath, for you will receive exactly what you deserve. However, the greatest reward is His good pleasure, for:
O you who believe! Heed Allah, and let each self look to what it has sent forward for tomorrow. Heed Allah. Allah is aware of what you do. Do not be like those who forgot Allah so He made them forget themselves. Such people are the deviators. (Surat al-Hashr, 18-19)
They said "Glory be to You!
