8. The Quran was written by Muhammad and copied from Christian and Jewish sources
The Qur'an was revealed to the Prophet Muhammad over a period of two decades, calling people to worship One Almighty God and to live their lives according to this faith. The Qur'an contains stories of Biblical prophets, because these prophets also preached the message of God. Stories are not merely copied, but the oral traditions are referred to in a way that focuses on the examples and teachings that we can learn from them.

9. Islamic prayer is just a ritualized performance with no heartfelt meaning
Prayer is a time to stand before God and express faith, give thanks for blessings, and seek guidance and forgiveness. During Islamic prayer, one is modest, submissive and respectful to God. By bowing and prostrating ourselves to the ground, we express our utmost humility before the Almighty.

10. The crescent moon is a universal symbol of Islam
The early Muslim community did not really have a symbol. During the time of the Prophet Muhammad, Islamic caravans and armies flew simple solid-colored flags (generally black, green, or white) for identification purposes. The crescent moon and star symbol actually pre-dates Islam by several thousand years, and wasn't affiliated with Islam at all until the Ottoman Empire placed it on their flag.
