The Quran is seen as the literal word of God and it's made up of 114 surahs or chapters and there's 6,236 verses, which must be spoken in Arabic and prayed in Arabic. That's critical as well. There's also something called the Hadiths, which are different accounts that were written down of Muhammad's life. The Quran is really a collection of ethics and morals and parables and ideas. And Muhammad's life is seen as how that is enacted in real life. And that forms the Hadiths and the Quran kind of Muslim law, Islamic law, which is called Sharia law. And we don't want to get political here because this isn't a political lecture, but Iran and Saudi Arabia actually practice Sharia law.
