Relics of Muhammad
Traditionally, Islam has had a rich history of the veneration of relics, especially of those attributed to the Islamic prophet Muhammad. There exists historical evidence that some of the earliest Muslims practiced the veneration of relics, and the practice continued to remain popular in many parts of the Sunni Islamic world until the eighteenth-century, when the reform movements of Salafism and Wahhabism began to staunchly condemn such practices due to their linking it with the sin of "shirk" (idolatry). As a result of the influence of these perspectives, some contemporary Muslims influenced by these ideologies have rejected the traditional practice of relic-veneration altogether. The most genuine prophetic relics are believed to be those housed in Istanbul's Topkapı Palace, in a section known as "Hirkai Serif Odasi" (Chamber of the Holy Mantle).
Topkapı Palace
The building where the arms and armor are exhibited was originally one of the palace treasuries ("Dîvân-ı Hümâyûn Hazinesi / Hazine-ı Âmire"). Since there was another ("inner") treasury in the Third Courtyard, this one was also called "outer treasury" ("dış hazine"). Although it contains no dated inscriptions, its construction technique and plan suggest that it was built at the end of the 15th century during the reign of Süleiman I. It subsequently underwent numerous alterations and renovations. It is a hall built of stone and brick with eight domes, each 5 x 11.40 m.
