What you are doing is actually illegal. you are distributing some fonts that have an exclusive license for specific companies. you are not helping designers by distributing fonts for free, but you are harming type designers who spend so much time developing Arabic fonts and you show no respect for intellectual properties. This can be lead to legal action against you. You should take this link out immediately.
The licences were taken out by the person who uploaded these fonts. The licences clearly - for many of these fonts- do restrict distributing these fonts or allow using them by other companies than the ones they are intended to.
