A man may do whatever he wants in this world, because he has ample opportunities to do so. For this reason, people harbour the misunderstanding that whatever they do must be right. They argue that, had they been wrong, they would not have achieved success by adopting the course that they did. Arguments of this kind are generally advanced by those who belong to the well-to-do class. But this is a serious misunderstanding. In this world, indulgence in any kind of behaviour may make headway because of the freedom given to human beings during their period of trial. But in the world of the Hereafter, the testing period will be over and, therefore, this opportunity will no longer exist for anybody there. In every age, the religion of the prophets was opposed and most of all by ancestral religion. Ancestors assume the status of the ‘great’ ones in the estimation of nations. As compared to them, the prophet of their own days appears lowly in stature. It therefore becomes impossible for them to renounce the religion of their great men in favour of that of a lesser mortal. But it is on account of their denial of these ‘small’ men that these nations have had to face horrendous punishments.
