As-salam 'alaykum:
Christians, Jews and the non-religious alike will sometimes attempt to assail Islam by pointing out the violence in the Qur'an, therefore throwing up their hands and saying that "since there's violence in the Qur'an, then Islam must be violent!" I know that neither Islam, Allah (swt), nor the Prophet (phub) are essentially violent - just the opposite. They take the Qur'an totally out of context, and by doing so do harm to themselves and the name of Islam.
We must not sink to that level. We must join with fair-minded Christians and Jews all over and denounce talk like this... it's the only way this world is going to be a better place, in my humble opinion.
Thanks, wa salam.
