in Arabic write مرحبا كيف حالكم أنا احب اللغة العربية

i agree with you Mumtaz this is not Arabic at all !!

O Allah! This is not even Arabic... These are English letters with Arabic numbers, have you ever heard of a language written in numbers? Ania, dear who taught you this? This is what I call the youth non sense language & it'll ruin your Arabic instead of making it better... Sorry but this is the truth! PLEASE Arabic teachers don't teach such a thing,, I don't even have a name for it, but please stop, it's even hard to read it.

Well, It is very recommended that you learn Arabic scripting or at least with an Arabic keyboard, I can help much with this.
