Islam is peace

I have been asked to shed some light on Islam as a peaceful religion. In view of the shortage of time, I can only address this subject briefly. Whenever one wishes to speak about Islam as a religion of peace, the question naturally springs to mind that whereas there are so many religions in the world such as Judaism, Christianity, Hinduism, Buddhism, etc., when it comes to finding out whether Islam is a religion of peace, why should Islam be the odd one out?
