Islam tells us that all religions revealed by God to His messengers brought true guidance from Him and, therefore, were one and the same. Therefore, Islam is not a recent religion. It is the same religion sent by God through His Prophets since the beginning of human history. So we can say that God had sent all the previously revealed books so that man might be informed of the nature of his life. The Quran, the last of the revealed books, endorses all the revealed books, which preceded it. But this endorsement applies to them only in their original, pristine versions.
