...So long as it's while you're killing infidels in a jihad. Jihad which, Muslims in the West keep telling us, is a peaceful internal struggle remember? In an audio recording released (it is believed) by Al-Zarqawi, he says:
"The killing of infidels by any method including martyrdom operations has been sanctified by many scholars even if it meant killing innocent Muslims. This legality has been agreed upon ... so as not to disrupt Jihad."
He goes on to state:
"Protecting religion is more important than protecting (Muslim) lives, honour or wealth. The shedding of Muslim blood ... is allowed in order to avoid the greater evil of disrupting jihad. God knows that we were careful not to kill Muslims and we have called off many operations in the past to avoid losses ... but we cannot kill infidels without killing some Muslims. It is unavoidable."
So it's all right then- he can go on killing Iraqi civilians, including young children, because he's carrying out a jihad against the infidels. So say the scholars of Islam. Thus far there have been no refutations from Muslim scholars anywhere.
