Khwarazmian dynasty
During the Khwarazmian dynasty, Razavi Shrine was paid much attention and some repair and decoration was made inside it. In this era (612 A.H./1215 A.D.), two very glorious embossed Thuluth (a large Naskh handwriting) inscriptions in form of square tile work were fixed on both sides of the shrine entrance-by the side of Dar al-Huffaz porch—in which the names and descent of Imam Reza back to Imam Ali were written. Some other inscriptions and three mihrabs (a special place for prayer-leader in mosques) belonging to this age exist in this holy complex.
