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.
