What is the Relation of Qur'an with Other Divine Books?

Prophets are not independent from each other. Rather, they are like links in a chain. The Divine Books that they deliver to people confirm each other. All of the prophets fought for the cause of tawhid and to establish a society based on rights and justice on earth.

The Qur'an affirms all the revelations throughout history. This is due to the fact that it is inclusive, not exclusive. Therefore those who believe in Qur'an believe in all the prophets and the books they brought and say: "We make no distinction between any of His messengers." (Baqarah, 2/285)

It should be noted here that the Divine Books' affirmation of each other of the is valid only for their uncorrupted originals. For example, the Qur'an does not affirm the present Torah, but its uncorrupted original. Therefore, the belief in the Qur'an requires the belief in the original of this book.

With the revelation of the Qur'an, there is no longer a need for the Torah and the Gospel. Because conditions changed drastically comparing to previous societies. The Qur'an has the most comprehensive content that meets the needs in parallel with the development of humanity. The Qur'an corrected the mistakes that were made in the previous books by its members, as well. It embraced the truths among them and drew attention to mistakes. This is due to the decisive identity of the Qur'an towards them.

One of the reasons for the revelation of the Qur'an is that Jews and Christians have serious disagreements among themselves. It is their misinterpretation of the Divine Books and their belief in these batil interpretations. For instance, in Judaism, the belief that the Israelites were the master race was adopted. Christians, too, had completely distanced themselves from the tawhid and went astray to the belief of the trinity. For these reasons mentioned above, Allah (swt) re-sent His religion with the Qur'an in its original form and abolished the previous books.

So, what should a Muslim's attitude be towards the information given in the previous Divine Books? If this information is in accordance with the Qur'an and sahih hadiths, it is accepted, if not, it is rejected. If this issue is not mentioned at all in the verses and hadiths, and if it does not contradict the basic principles of Islam, then it is neither accepted nor rejected. As a matter of fact, we are advised to say: “Say, [O believers], "We have believed in Allah and what has been revealed to us and what has been revealed to Abraham and Ishmael and Isaac and Jacob and the Descendants and what was given to Moses and Jesus and what was given to the prophets from their Lord. We make no distinction between any of them, and we are Muslims [in submission] to Him." (Baqarah, 2/136)
