Have you tried Google Fonts ?
You can easily import fonts into your web application, for example by adding the following code to the header:
<link href="http://fonts.googleapis.com/earlyaccess/droidarabicnaskh.css" rel="stylesheet" type="text/css" />
then you can use the font in your CSS, for example:
body {
font-family: 'Droid Arabic Naskh', 'Monda', sans-serif;
}
