This irreplaceable 800 year old minbar was destroyed by an Australian man partly influenced by Armstrongism named Denis Michael Rohan.
Here is how Wikipedia describes the origins of this historical minbar.
The minbar ("pulpit") of the mosque was built by a craftsman named Akhtarini from Aleppo on the orders of the Zengid sultan Nur ad-Din. It was intended to be a gift for the mosque when Nur ad-Din would capture Jerusalem from the Crusaders and took six years to build (1168–74). Nur ad-Din died and the Crusaders still controlled Jerusalem, but in 1187, Saladin captured the city and the minbar was installed. The structure was made of ivory and carefully crafted wood. Arabic calligraphy, geometrical and floral designs were inscribed in the woodwork.Tragically it was destroyed by Denis Michael Rohan, an Australian man partly influenced by Armstrongism. He was a subscriber to The Plain Truth. This terrible act continues to poison relations to this day.
This is what happened in regards to the minbar afterwards.
After its destruction by Rohan in 1969, it was replaced by a much simpler minbar. In January 2007, Adnan al-Husayni—head of the Islamic waqf in charge of al-Aqsa—stated that a new minbar would be installed; it was installed in February 2007. The design of the new minbar was drawn by Jamil Badran based on an exact replica of the Saladin Minbar and was finished by Badran within a period of five years. The minbar itself was built in Jordan over a period of four years and the craftsmen used "ancient woodworking methods, joining the pieces with pegs instead of nails, but employed computer images to design the pulpit [minbar]."Recently there has been much justified outrage and sadness at the recent acts of vandalism against historical artifacts by Abu Bakr al Baghdadi's lackeys (ISIL). How frightening it is that a man influenced by Armstrongism should do something like that as well.
