*5) This is about those people who were being obstinate and stubborn with regard to the message of the Holy Prophet and had made up their minds not to listen to him at all. This is because: They have already deserved the torment; therefore, they do not believe." It means: "The people who do not heed the admonition, and persist in their denial and hostile attitude to the truth in spite of the final warning from Allah conveyed through the Prophets, are themselves overwhelmed by the evil consequences of their misdeeds and deprived of every opportunity to believe. " The same thing has been expressed more clearly in verse 11 below: "You can only warn him who follows the admonition. and fears the Merciful God though he cannot see Him. "
