get comments and get posts in loop

I need to get posts done by specific users and get also comments done to these posts, so far I can get the posts and comments but can’t get how to do it in loop properly, because now I get the same comments displayed for each post no matter to which posts they actually belong to…

So here is the code…loop inside another one, I am now quite sure that is the way it should…

So the output in my case: list of posts + each posts get ALL the comments which have ever been done…

I want to get post + only its comments in a loop
(I will put only php)

        <?php $posts = get_recent_posts_by_author_role('tenant');
                        foreach($posts as $post) {
                            $title=$post->post_title;
                            $perma_link=get_permalink($post->ID);
                            $img_post=get_the_post_thumbnail($post->ID);
                            $author_name=$post->post_author;
                            $content_post=$post->post_content;
                            $date=$post->post_date;
                            $content_style="comment_text"; 

                        ?>

<?php $comment=get_comments($post->ID);
                                foreach($comment as $com){

                                    $com_author=$com->comment_author;
                                    $com_date=$com->comment_date;
                                    $com_content=$com->comment_content;
                                    global $authordata;
                                    $author_roles=$authordata->roles;
                                    ?>

<?php  }?>
<?php  }?>

get_comments accepts an array of arguments, you are passing an integer.

If you want to retrieve all comments for a post use:

get_comments( array('post_id' => $post->ID, 'status' => 'approve') );

To get an already formatted comment list, is easier use the wp_list_comments() function, instead of another foreach cycle (code from codex):

  echo '<ol class="commentlist">';
  //Gather comments for a specific page/post 
  $comments = get_comments(array(
    'post_id' => $post->ID,
     'status' => 'approve'
  ));
  wp_list_comments(array(
    'per_page' => 10, // Allow comment pagination
     'reverse_top_level' => false //Show the latest comments at the top of the list
   ), $comments);
  echo '</ol>';
