What is "zarih"

A zarih is a lattice work, usually gilded, that encloses a grave in a mosque or other Islamic tomb. They are large cubical or rectangular structures with decorated posts at the corners and in the middle of the sides, the walls of the Zarih are filled with verses of the Quran, names of Holy Figures and other exquisite artwork. A zarih is often made as a waqf with its creators demanding no pay for their work. Notable ones are found in the Imam Husayn Shrine, the Al Abbas Mosque, the Sayyidah Ruqayya Mosque, the Imam Ali Mosque, and elsewhere.
