Dear scholars, As-Salaam `Alaykum. Recently I was visited by a Christian missionary at my home. We had a good discussion on Islam and Christianity. When I told him that the Bible was changed and is not in its original form, he did not agree with me. He told me that there were many ancient manuscripts of the Bible in its original Hebrew and Greek languages available today. He also told me that according to the Qur'an, Bible is the word of God and the word of God cannot be changed. The Qur'an says in (6:115) "none can change His words..." and in (10:64) "No change can there be in the words of Allah." Please help me to understand the meaning of these Qur'anic verses. On the one hand the Qur'an says that the Bible was from God and God's words could not be changed and on the other hand it says that Bible was changed. How should we explain these two different verses of the Qur'an? Jazakum Allah khayran.
