Since my personal religion (no one understands it
) is a mixture of Islam, Christianity and Judaism, I want to read all the three Holy Books. I've read the Koran (because it has less pages than the Bible and the Torah, I guess) already, I'll soon start reading the Bible and the Torah. Grizabella, if you want to start reading the Koran, I recommend you the version of Rashad Khalifa. Most Koran translators are influenced by traditional sources and therefore they misinterpret many lines in the Koran - R.K. clearly rejects the traditional sources, since they are the reasons why women in Arabic countries are often treated badly. Have fun!
(And, Grizabella, I find it sad too that many people don't even read their Holy Books, know from their religion only from hearsay and assume they know it all. Good point!)
