" I think I can say quite clearly and explicitly that the various types of actions which we call terrorism are not only not encouraged, they are explicitly forbidden by Sharia Law .. It is true that waging war is a religious obligation, but precisely because it is a religious obligation , it is regulated by religious law .. even medieval Sharia texts go into astonishing detail into what is permitted and what is not permitted .. The Sharia requires that proper warning be given before beginning hostilities .. it has elaborate regulations regarding the treatment of civilians, the women and the children and the aged .. it discusses how prisoners should be treated .. what weapons should be used .. they discuss and for the most part reject the use of chemical weapons.
