waAlaykum AsSalaam waRahmatullahi waBarakatuhu,
I'm afraid that I don't have specifics at the moment, but I have heard that a university in Jordan (the university of Jordan?) runs short-term courses, and can even help arrange accommodation.
I don't think that Egypt would be the best place to go because of the dialect spoken over there (and the tendency to turn the jeem into a g ;D), even though you will be studying at a school you will be practicing with the general population, no?
I have been thinking of studying this abroad myself, and people have recommended Syria for this, as I have been told that they speak a high standard of arabic over there.
and pathetic quasi- arabinised everything else
Ouch
