In their 1400 year history, they've literally "knifed to death" at least 100 million more than they have shooting or blowing up people with bombs. 80 million alone in the conquest of India. Then we have the millions of assyrians, greeks, africans, ect. The weapon of choice for muslims is the knife/sword. When they kill captives, they generally behead them and not shoot them.
So did the Romans...Vikings....Zulu....Greeks....Egyptians..
Here is a fun fact, many armies chose swords before guns were invented and widespread....quirky.
