Criteria For Believing in the Hereafter

One of the necessary requirements for making it to Paradise in the Hereafter is that one needs to believe in the Hereafter.

2:62 Surely, those who believe, those who are Jewish, the Christians, and the converts; anyone who (1) believes in GOD, and (2) believes in the Last Day, and (3) leads a righteous life, will receive their recompense from their Lord. They have nothing to fear, nor will they grieve.

إِنَّ الَّذِينَ آمَنُوا وَالَّذِينَ هَادُوا وَالنَّصَارَىٰ وَالصَّابِئِينَ مَنْ آمَنَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَعَمِلَ صَالِحًا فَلَهُمْ أَجْرُهُمْ عِنْدَ رَبِّهِمْ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ

However, for a person to prove that they really believe something, then their actions should correspond with their stated belief; otherwise, the claim is nothing but lip service. For instance, if an investor claims that the market is going to crash, then we would expect that his position in the market would match this belief, but if we see that it doesn’t, then it is a sign that he doesn’t really believe what he states.

At the beginning of the Quran, God informs us of those who claim to believe in the Last Day, yet they do not.

2:8 Then there are those who say, “ We believe in GOD and the Last Day,” while they are not believers.

وَمِنَ ٱلنَّاسِ مَن يَقُولُ ءَامَنَّا بِٱللَّهِ وَبِٱلْيَوْمِ ٱلْـَٔاخِرِ وَمَا هُم بِمُؤْمِنِينَ
