Timur began the construction of his mausoleum in 1404 on the site of the madrassa and khanagah (monastery) of his grandson Muhammad Sultan. Timur was later buried there and his tomb is marked by a dark green jade cenotaph of striking beauty. The Gur-i Mir is one of the most imposing buildings in Samarkand; the woodwork, stone carving and tilework is of the highest quality. The cutting of marble and engraving of inscriptions for the building of a mosque in Samarkand is shown in a miniature of the Zafarnama of circa 1480 in the Walters Art Gallery, T.L.6 1950 (360a).
The Umniakov expedition worked in Samarkand from 1920-1928. They were involved in the conservation and restoration of several Islamic monuments in Russian Turkestan, principally working on the Gur-i Mir. The marble panels with hadith inscriptions such as the present piece, encircled the interior walls of the mausoleum. Today up to a quarter of the panels are replacements.
