The Messenger's duty is to warn:

                                The general warning of the Qur'an:                              
                             | 
                          
                                                  
                            
                              
                              
                                With Allah is the knowledge of the Hour (the last hour of the world):                              
                             | 
                          
                                                  
                            
                              
                              
                                The end of the world is at an appointed time:                              
                             | 
                          
                                                  
                            
                              
                              
                                Only the unbelievers will witness the horror of the end of the world:                              
                             | 
                          
                                                  
                            
                              
                              
                                The believers fear the evil reckoning, they do not think that they will be saved, but they hope to be saved:

                                In the context of verses 42, 43...46; a reference to the unbelievers who defiantly ask about the time of the end of the hour/world, confident that it will never happen:                              
                             | 
                          
                                                  
                            
                              
                              
                                The Hour/The End of the World and therefore the Resurrection:
