I saw last night on either Fox or CNN that European authorities are investigating a Muslim calendar that featured a plane crashing into Manhatten and the words "We place our fate in God's hands" for the month of September. The implication was that the calendars had been out for some time, thus predicting the attack.
They showed a picture of the calendar page in question. The actual copies of the calendar were found in a Muslim school in Belgium or something like that.
