Really great site for learning Arabic through simple short dialogues. I found it on itunes: http://www.arabicpod.net/learnarabic
you can download a number of dialogues for free through itunes or the website – PDFs are also available along with other useful resources. Altogether a great site – May Allah bless their efforts.
