Some people believe that there is no such thing as hereafter. They believe that people are just like candles. When they die, they simply vanish, like the light of the candle being blown. No responsibility or whatsoever for what they had done on earth. Thieves and murderers as well as pious people will end up in the same situation.
Believing in the existence of the hereafter is one of the Godly beliefs. Allah (God) warns human being about the existence of hereafter in the Qur'an chapter 6 verse 32, "What is the life of this world but play and amusement? But the best is the home in the hereafter, for those who are righteous. Will ye not then understand?". Qur'an chapter 29 verse 64, "What is the life of this world but amusement and play But verily the home in thereafter, that is life indeed, if they but knew." And God says in the Qur'an chapter 17 verse 10, "And those who believe not in the hereafter, (it announceth) that We have prepared for them a penalty grievous (indeed)."
But as a matter of fact, even without the verses from the Qur'an, it is logical for a person to believe in the hereafter. All he has to do is to function his mind and heart or contemplate spiritually.
We all agree that a person must be responsible for every action he makes. If we spill coffee to the floor, we must clean the floor. If we lose our parents' valuable item, we must replace it. When a person hurts someone physically, he must be responsible, at least by paying for the medication. When a person lies, he must face the consequence of his lying. When person steals or kills or rapes someone, he must face the laws for his evil deeds. So, basically, a person must be responsible. However, what if a person doesn't have a chance to be responsible or to receive the consequence of his actions when he was still alive on earth? Let's say a person who has done corruption for many years but never get caught or never get punished on earth and then suddenly he dies due to heart attack. Or a killer who never get caught and punished until he dies at his old age. It is just not fair, it is just not logical and it is against the common sense that such a person will just disappear from this world with his evil deed without being accounted for his action. On the contrary, it is logical that he will be accounted for his evil deeds 'somewhere' and 'somehow'. And that 'somewhere' and 'somehow' is the hereafter, in the form of either heaven for good deeds or hell for bad deeds.
Let's contemplate further. Imagine there are two dead bodies in front of us. One dead body is a kind, pious person who used to implement the teachings in the Qur'an when he was still alive. The other dead body is a bad person who used to disobey the teachings of God in the Qur'an. He used to lie, get angry, hurt people's feelings with nasty words and attitudes, and did things based on his desires. Those two dead bodies were wrapped by white, kafan fabric, special fabric for wrapping dead bodies. They both look the same, nothing different. When the faces are totally covered by the fabric, the living ones couldn't make the difference which one was a good person and which one was the bad one. It is against the common sense that the two people will just vanish or will not receive the consequence of their actions which are very different to each other. So, the only perfect place for complete and fair calculation is the hereafter. God will give reward for the good deeds that haven't been rewarded on earth and God will give punishment for the bad deeds that haven't been paid on earth. In short, the hereafter with heaven and hell is the manifestation of God's attribute of being The Most Just.
Knowing that the hereafter exists is not enough because knowing will not result in action. Knowing lies in the brain and if it stays there, it will not give benefit at all. But bear in mind that knowing (knowledge) is important in a sense that it is the 'raw material' for being processed further in our heart. What is the most important is believing or having faith that hereafter exists. The believe, which lies in the heart, will result in action. What is the prove that someone does believe in the hereafter? Simply take a look at his behavior or action.
If a person still likes slandering or gossiping about other people, it means his belief of the existence of the hereafter is not yet strong. Prophet Muhammad (peace be upon him) said, "Gossiping feels good on earth, but it can lead a person to hell in the hereafter."
If a person still feels in his heart that he is better than others it means his belief of the existence of the hereafter is not yet strong. God forbids human being to be arrogant.
If a person still does many bad things such as stealing, lying, cheating, hurting other people, it is then clear that he doesn't have strong belief, or he doesn't believe at all, of the existence of the hereafter.
And if a person still refuses to help others or rejects to do good deeds, it means that he doesn't have strong belief, or he doesn't believe at all, of the existence of the hereafter. God promises in the Qur'an chapter 43 verse 72, "Such will be the garden (heaven) of which ye are made heirs for your (good) deeds (in life)." Furthermore in chapter 2 verse 82, "But those who have faith and work righteousness, they are companions of the garden (heaven). Therein shall they abide (forever)."
Thus, it is clear that if a person has a low quality of belief of the existence of the hereafter, his actions or behavior will not be good as God says in the Qur'an chapter 16 verse 60, "To those who believe not in the hereafter applies the similitude of evil…"
Having a solid belief that hereafter exists will undoubtedly drive us to do as many God's rules as possible. It will be much easier for in accepting and comprehending the rest of God's rules.
Please recall the journey of human being:
soul world —-> mother's womb world —-> this world —-> grave world —-> hereafter (heaven and hell)
In the end, there are only two places that human being will arrive. Make sure that we have as many Godly beliefs, including the belief that hereafter exists, so that we don't end up in the wrong place…
