15. This is to impress that if a person adopts the right way, he does not do any favor to God or His Messenger or a reformer but he himself gets its benefits. On the other hand, if a person deviates from the right way, he can do no harm to God or His Messenger or a reformer, for they desire only to protect men from wrong ways and guide him on to the right way, and not for any selfish ends. Therefore, the right course for a wise man is to adopt the righteous way when it becomes distinct to him what is truth and what is falsehood. On the other hand, if he rejects truth because of his prejudices and self interest, he will be his own enemy and not a well wisher.
16. The Quran has laid great stress on the doctrine of personal responsibility at several places, for one cannot follow the right way scrupulously without understanding fully its implication. It means that, everyone is solely responsible for his moral conduct and is accountable to God as an individual in his own person and no other person can share the burden of responsibility with him. As an instance, we take the case of a particular action or a particular way of conduct in which a generation or a community of a large number of people had collaborated. When the people will assemble before Allah on the Day of Judgment, their collective action will be analyzed so as to lay the burden of its responsibility on each and every person who had been conducive to it, and rewarded or punished in accordance with it. Neither will a person be punished for the part another had played in its performance nor shall the burden of the sin of one individual be laid on the shoulders of another. This doctrine has been emphasized over and over again so that a wise man should not act in imitation of another or justify his own conduct by similar deeds of others. If a particular person feels the sense of his own responsibility, he will act in such a way as to come out successful on the Day of Judgment, regardless of what the others do.
17. This is another doctrine which has been impressed on the minds by the Quran in different ways. This is to emphasize the basic importance that a Messenger has in the dispensation of divine justice because this is determined in the light of the message brought by him. This will be employed as an argument in favor of or against the concerned people. Otherwise the infliction of punishment on the people would be unjust for in that case they could argue that they should not be punished as the knowledge of the righteous way had not been conveyed to them. But after the message had been conveyed to a particular people, and they had rejected it, there would be left no excuse for them.
It is an irony that instead of accepting the message some people are misled by reading verses like this and they ask such absurd questions: What will be the position of those, who might not have received the message of any Prophet? The wise course for such persons would have been to ask themselves what their own position will be on the Day of Judgment, because they themselves had received the message. As regards to other people, Allah knows best who has received the message, and when, how and to what extent and what attitude a certain person adopted towards it. In short, Allah alone is aware of whether a particular person received the message in such a way as to fulfill the required condition for punishment.
