Shaykh Yusuf Qaradawi, Qatar; Tariq Bishri, Egypt; Muhammad S. Awwa, Egypt; Fahmi Huwaydi, Egypt; Haytham Khayyat, Syria; Shaykh Taha Jabir al-Alwani, U.S.:

All Muslims ought to be united against all those who terrorize the innocents, and those who permit the killing of non-combatants without a justifiable reason.  Islam has declared the spilling of blood and the destruction of property as absolute prohibitions until the Day of Judgment. ... [It is] necessary to apprehend the true perpetrators of these crimes, as well as those who aid and abet them through incitement, financing or other support. They must be brought to justice in an impartial court of law and [punished] appropriately. ... [It is] a duty of Muslims to participate in this effort with all possible means.  (The Washington Post, October 11, 2001, http://www.washingtonpost.com/wp-dyn/articles/A40545-2001Oct10.html )
