Looking thru the code, i found in Subs-Portal.php (starting Line 690) the funktion called "BookOfSinan".
What exactly doing this function
function BookOfSinan()
{
global $context, $scripturl;
echo '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"', $context['right_to_left'] ? ' dir="rtl"' : '', '>
<head>
<title>The Book of Sinan, ', @$_GET['verse'] == '3:17' ? '3:17' : '1:15', '</title>
<style type="text/css">
