هديتي لكم في القواعد

السلام عليكم و رحمة الله و بركاته
here is my first participation in this section which is a powerpoint in English and Arabic for grammer. I found it in a site but I can't remember exsactly from where. I'm also not sure if it is in this site too ( to avoid repetition). It is realy very useful and in addition it contains examples and explanation in Arabic. it is well organized .
