These trees are one of the only extant naturalistic features in Mamluk architectural decoration.[9] The mihrab is made of polychrome marble and has friezes of small niches with blue-glass colonettes on the side framing its upper edge. The dado has similar friezes. The walls are decorated with marble mosaics centered by a Kufic inscription of Allah, and on the northern wall there is a panel made totally of white marble inlaid with green gypsum.
