access to upcoming post even if user isn’t logged in wordpress

Solution:

I found answer to my question, all I wanted is to have upcoming posts which will be available to users even if they aren’t published yet. Solution is taken from HERE.

Just pasted below code in my functions.php file and it is working:

function show_future_posts($posts){
   global $wp_query, $wpdb;
   if(is_single() && $wp_query->post_count == 0)
   {
      $posts = $wpdb->get_results($wp_query->request);
   }
   return $posts;
}
add_filter('the_posts', 'show_future_posts');
