Judaism
Rabbinic Jews also believe that there is another part of the Torah besides the five books of Moses. It is called the Mishnah, also called the Oral Torah or Oral Law.  It explains how to follow the laws written in the 5 books.  There is a commentary (explanation) of the Mishnah, called the Gemara.  Together, the Mishna and the Gemara make up the Talmud. But Karaite Jews believe that there is no additional Torah besides the five books of Moses.
