بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ
A fundamental concept in Al-Quran is the emphasis on the belief in ‘akhirat’ i.e hereafter. This belief is fundamental in character building of the believers. A gold test to check whether we actually believe in this concept or not will be, in a situation in which we are absolutely certain that we will get away from doing a certain evil thing without any fear of repercussion whatsoever, however, we still refrain from doing that evil thing, with the certainty that we will definitely be held accountable for our deed in the hereafter. If we pass this test, then we do actually have belief in ‘akhirat’.
General observation is that many people when they know that they are not seen by anybody and don’t have fear of being caught, they go ahead in carrying out an evil act, even though they do lip service to their belief in ‘akhirat’.
A very useful tool for the believers in character building is to always be conscious of Allah as if a video of all their actions is being made all the time with the added dimension of what is in their hearts and this video record of their deeds will be on display on the day of hereafter and they will be held accountable for all their deeds. So, if you are able to refrain yourself from doing a bad thing primarily due to absolute belief of your accountability by Allah then you have true belief in ‘akhirat’.
2:62 إِنَّ الَّذِينَ آمَنُوا وَالَّذِينَ هَادُوا وَالنَّصَارَىٰ وَالصَّابِئِينَ مَنْ آمَنَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَعَمِلَ صَالِحًا فَلَهُمْ أَجْرُهُمْ عِندَ رَبِّهِمْ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ
Verily, Those people who believe, and those who are Hood (Yahood), and the Nasara and the Sabians,- any who believe with Allah and the Last Day, and work righteousness, shall have their reward with their Lord; on them shall be no fear, nor shall they grieve.
For people belonging to different groups of characteristics, the fundamental requirement of them is to be conscious to the concept of accountability for all their actions they do in the world, and be conscious of an all powerful and cognizant God, who will make them accountable for their deeds.
A society with majority of people believing in accountability will definitely show signs of goodness, well being and people taking care of others. If a society shows signs of depravity, elevated crimes and degradation of humanity then definitely they don’t have belief in ‘akhirat’, no matter what religious label they put on themselves.
