The Bible contains far more verses praising or urging bloodshed than does the Koran, and biblical violence is often far more extreme, and marked by more indiscriminate savagery. The Koran often urges believers to fight, yet it also commands that enemies be shown mercy when they surrender. Some frightful portions of the Bible, by contrast, go much further in ordering the total extermination of enemies, of whole families and races - of men, women, and children, and even their livestock, with no quarter granted.

And fight them until there is no more Fitnah (disbelief and polytheism: i.e. worshipping others besides Allâh) and the religion (worship) will all be for Allâh Alone [in the whole of the world[]]. But if they cease (worshipping others besides Allâh), then certainly, Allâh is All-Seer of what they do
