The word 'Torah' means 'teaching' or 'law' and includes the first five books of Moses.
Christians have called 'The Old Testament', the 'Tanakh' that the Jewish people prefer to use for the Hebrew Bible. The acronym is formed from the initial Hebrew letters of the Tanakh's three traditional subdivisions. The reason for the Christians' calling the Old Testament' is that they consider it as the 'Old Law' abrogated by the New Testament. However, the Jews are convinced that as they happen to be the Chosen People, their Covenant will remain in force forever. They consider the Christians' approach derogatory.

The Jews accept that the Torah formed of five books, also called Pentateuch by the Greeks, had been revealed to Moses, but that the other books called Tanakh that make up the 'Old Testament' were also revelations hat had been committed to paper by the Israelite prophets.

The Christians claim that the Old Testament (Tanakh) had been given to the Israelites and contained sacred texts, but as they have been given the New Testament, the former Testament had become null and void. The Qur'an, in many of its verses, confirmed that the Torah had been revealed by God. It enjoined the Jews and the Christians to abide by their own books.« It was We who revealed the law (to Moses): therein was guidance and light. (Surah 5/44) "We believe in the revelation which has come down to us and in that which came down to you;» (Surah 29/46)
