Try this:

<li><h2><?php _e('حالیہ'); ?> <?php _e('تحاریر'); ?></h2>
<ul>
<?php wp_get_archives('type=postbypost&limit=7&before=|&after=|'); ?>
</ul>
</li>

You might need to use the url-encoded equivalent for the "|" character....

The function "wp_get_archives" appears in template-functions-general.php in your wp-includes folder. The function can take up to 6 arguments.
