Salaam: I am posting this in the Islam section as the target audience for the discussion is only Muslims. Jews and Christians are welcome to respond, but I want an answer from an Islamic perspective. I do not expect Jews and Christians to agree with the proposed claim. So, I have read translations of the interpretations of the meaning of Noble Qur'an as well as the Old and New Testaments. And, my personal conclusion is that Allah SWT is not saying in the Qur'an that the both biblical testaments are corrupt 100%. Rather, Allah SWT is saying this: a. Jews received the Torah, but took something else as the guide that is not equivalent to the Torah. b. Christians have corrupted the New Testament that deviates from the true Message by preaching the concept of trinity When Allah SWT says that the Jews are using something as replacement for Torah, I am understanding this as the Talmud traditions and the books included in the Old Testament that are not part of the original books of Moses. So, in regards to the Jews the charge would be that they are using extra stuff that is not part of the Revelation. When Allah SWT speaks of Christians, the message appears to be more clearer in that the claim against them is their understanding of the nature of God and their belief in Jesus' "divinity." Are there any sources that either support or go against my understanding about this? I have read about the Roman Church adding, editing or deleting biblical verses and I do know that various Christian sects use different number of books for the Bible. There is also the apocrypha books too.
