From one of many sites accessed through google news:

Recently, though, Islam has criticized terrorist acts, including the Sept. 11, 2001, attacks and the school seizure in Beslan, Russia, earlier this month that left more than 300 dead, nearly half of them children.

In a statement on his Web site, he wrote, "Crimes against innocent bystanders taken hostage in any circumstance have no foundation whatsoever in the life of Islam and the model example of Prophet Muhammad, peace be upon him."

After the Sept. 11 attacks, Islam issued a statement saying: "No right thinking follower of Islam could possibly condone such an action: The Quran equates the murder of one innocent person with the murder of the whole of humanity."
