But the similarity can't be extended too far. The Qur'an was revealed to one person - the Prophet Muhammad (PBUH), and to nobody else. It is the final and supreme self-expression of God to humanity. God, in a sense, is incarnate in the pages of the Qur'an - every word, every letter of the text, especially in the original Arabic, is sacred as a result. It is a terrible blasphemy to disturb or damage the text of the Qur'an (or even, in some interpretations, a text containing text from the Qur'an ... or even the word Qur'an itself!). This is the Book of books. Other religions (Christianity, Judaism) also have revelations from God. Prophets from God have spoken to us before Muhammad (PBUH), and have contributed to scriptural documents (hence the Muslim designation of Christians and Jews as people of the book). But the Holy Qur'an is special.
The Bible is not as important to Christians as the Qur'an is to Muslims. This is for a very good reason: to Christians, Jesus is the final and ultimate expression of God to humanity, and the Bible merely points the way to him. Damaging a Bible might be deeply offensive to Christians. However, it wouldn't affect them the way damaging a Qur'an would affect Muslims. In a Muslim country like Pakistan, you could cause a riot (literally!) by deliberately damaging a Qur'an. Such an act would not just be an attack on the faith, and not merely offensive to believers: it would be an attack God himself. My old Bible is all marked up with pen, marginal notes, words circled etc. I doubt there are many Qur'ans like that.
Christians who take the Bible too seriously, in fact, are sometimes accused of "Biblolatry" - Bible worship - which is a form of idol worship. Don't get me wrong here: the Bible is from God according to Christians. It's just not from God in the same way, for Christians, as the Holy Qur'an is from God according to Muslims.
This is not surprising. The Bible is not the work of one person. It was written by many different people over thousands of years, and gathered together by editors into a single, more or less coherent text. To understand it fully clearly requires a basic knowledge of the various cultural backgrounds of the different peoples whose cultures produced it, and the kinds of literature they employed in their self-expressions. One of these self-expressions is the idea that a Messiah would come to save the people and lead them. The Bible is not from that Messiah, however. It is, in part at least, about him.
So the different religions approach their basic texts differently.
Nevertheless, the use of the text can be similar! Look at the texts in the image here (or look at this bigger image). They both talk, in surprisingly (is it surprising?) similar terms, of the role of the scriptural document in the life of the believer. These religions, in the end, might have more in common than people nowadays tend to believe.
At least, that's what I think.
