“The ruling to kill Americans and their allies Civilians and military – is an individual duty to every Muslim who can do it in any country in which it is possible to do it—to comply with God’s order to kill the American and plunder their money wherever and whenever they find it. We also call on Muslims Ulema, leaders, youths, soldiers to launch the raid on Satans US troops and the devil’s supporters allying with them.”
