Islam Denounces Terrorism Terrorism is a crime against humanity. It is a brutal attack on innocent people. Islam is a religion that means "peace". In the Koran, the Holy Book of Islam, God commands believers to bring peace and security to the world. Terrorism and all other mischief on Earth are the very acts that Muslims are commanded by God to stand against. The Islamic morality is the cure for terrorism, not the source of it. Those who resort to or support terrorism in the name of Islam are in a great error. They are committing a crime which God has cursed in the Koran. All true Muslims denounce terrorism of any kind, and share the sorrows of its victims.
