Below is an excerpt from a website about Fethullah Gulen in which Mr. Gulen's condemnation message about the unfortunate 9/11 attacks. You can also find out the authentic picture of Fethullah Gulen's message on "Washington Post" which was published ten days after 9/11.
... Fethullah Gulen was the first Muslim scholar who publicly denounced the 9/11
attacks, just a few days after these unspeakable acts. As far as we
knew, his public condemnation message was published in the Washington
Post. We searched the exact quote online -contrary to conventional media
reporting, which is not famous with amplifying the tolerant voices,
online resources have always been more diverse. Thus, we were sure that
we’d be able to find the message in a few seconds, or just in a
millisecond, as Google advertises, but to our surprise, nothing popped
up! We looked for hours and could not find the exact quote of Fethullah
Gulen’s condemnation message. There were many websites letting people
know that a denouncement exists, but none could provide it to their
readers. Some of the intellectuals in the room became curious about the
statement. Could it be an urban legend that a prominent Muslim scholar
had condemned the 9/11 attacks just a few days after the events and in
Washington Post?
I took the privilege of searching the authentic condemnation message
and found it. Unquestionably, my first stop was the Library of Congress.
Though there seems to be a consensus of online resources that the
condemnation message exists, there have been different dates flying
around. Some said it was published on September 12th, 2001, others
argued Sept 18th, 2001 was the exact date. None was true. After digging
through all of the issues of the Washington Post from Sept 12th through
the end of the month, I found Mr. Fethullah Gulen’s message, dated September 21st, 2001.
Below is the authentic condemnation message of the 9/11 terrorist
attacks by Mr. Fethullah Gulen, published by the Washington Post on
September 21st, 2001.
