When every effort has been made to make them understand the Truth in the most rational ways, when instances have been cited from history to show them the evil results of the denial of the Hereafter, when the dreadful fates suffered by the other nations in consequence of their rejecting the Prophetic messages have been brought to their notice and yet they are disinclined to give up their stubbornness, they should be left alone to gloat over their follies.
