What parts of the Bible ?

Hello again ,
Ok so next question if that's ok . I understand that Muslims refer to the majority of the old testament and the gospels ?
Secondly which version of the Bible is the most reliable ?
And last of all is there an "all in one " I can buy like old testament , gospel and Quran ?
Thank you again for your time .

We Muslims know that only the Quran tells the last, final and the reliable truth. The Bible is corrupted, it means in it people have changed the message of Allah. So if you want to know more about the right path, you should read the Quran only.
