The page you are requesting cannot be found or correctly determined. In case you are accessing a page that ends in something like /3.htm, try removing it and check if it works. So for example, you are accessing http://www.al-islam.org/it/abcisl/13.htm, try visiting http://www.al-islam.org/it/abcisl instead.
Also, if you are visiting a url that has "sid=343" or something similar in it, please try removing it and check again. So for example, you are accessing http://www.al-islam.org/action.php?sid=322253293&action=go&id=15804, try visiting http://www.al-islam.org/action.php?action=go&id=15804 instead.

Rest assured, we are trying to fix ALL the page not found errors that you are facing and hope to have a stable site running as soon as possible. Please check back in a couple of weeks and (hopefully), the url you are accessing will work again!
