The interior of the mosque was quite dark. I pushed the ISO up to 9000 to get a decent hand held photo. Tripods were not allowed. Tourists were only allowed in one part of the mosque as worshipers were in the other side. The lens used was a Nikon 16-35mm f/4. At 16mm it was not wide enought to include the whole ceiling. The wires you see hanging from the ceiling hold the interior lights.
