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 Dormitory of the Royal Pages ("Hasoda Koğuşu") houses the Imperial Portraits Collection ("Padişah Portreleri Sergi Salonu") was part of the Sultan's chambers. The painted portraits depict all the Ottoman sultans and some rare photographs of the later ones, the latter being kept in glass cases. The room is air-conditioned and the temperature regulated and monitored to protect the paintings. Since the sultans rarely appeared in public, and to respect Islamic sensitivity to artistic depictions of people, the earlier portraits are idealisations. Only since the reforms of the moderniser Mahmud II have realistic portraits of the rulers been made. An interesting feature is a large painted family tree of the Ottoman rulers. The domed chamber is supported by pillars, some of Byzantine origin since a cross is engraved on one of them.
