Do the books of Tawrat, Injil and Jabur stiil exist?

These kitabs (books) are not still unchanged. Jews-Christians have deformed all of these from the real books. The bible which can be found at present is not the real Injil Shareef. Christians have changed it. So, at present if anyone quotes from these books, then that will not be allowed (jayiz) to accept. (Various books of Tafseer and Tarikh)
