Arabic is the chosen medium for the conveyance of the Divine message. It is the key to understanding Islam and its sciences, and no serious student of Islam can do without it. These are my notes to a crash course in Arabic grammar I last taught in 2006. It is an unfinished work as I got side-tracked by other projects, but I am still posting it for the benefit of fellow students.

Very nicely written. Jazaka Allahu Khayr.
Thank you and may Allah reward you for sharing this.
This is a pretty good software to learn Arabic on your own – http://7a862fjinsay0oe3szkfqdn63m.hop.clickbank.net/
