And ulema [Muslim legal scholars] have throughout history unanimously agreed that the jihad is an individual duty…On that basis, and in compliance with Allah’s order, we issue the following fatwa to all Muslims: The ruling to kill the Americans and their allies—civilians and military—is an individual duty for every Muslim who can do it in any country in which it is possible to do it…We, with Allah’s help, call on every Muslim who believes in Allah and wishes to be rewarded to comply with Allah’s order to kill the Americans and plunder their money wherever and whenever they find it.
