There's no such thing as latest version of qur'an..It has always been the same one for 1,600++ years now.
You know that there are other few religions that worship Allah as well right? Like Christian, Judaism etc. so those are ahli Kitab. However, that rule only applies to practising ahli kitab. Like for e.g. they must follow the bible line by line.
I'm sure that you'll have more questions on this ahli Kitab thing. However, I will not explain further on this in this thread as this is a sensitive issue. PM sure cannn...
