Topkapı Palace, both the administrative and residential heart of the Ottoman Empire, houses invaluable sacred relics which are kept in Has Oda, the Sultan’s Privy Chamber. Precious belongings of Prophet Muhammad (s.a.w.) and objects that belonged to prophets including Prophet Muhammad, Prophets Moses and Joseph, and Prophet Muhammad’s (s.a.w.) daughter, son-in-law, and companions along with the key to Ka'bah have been preserved at Topkapı Palace for 500 years. The most important of the relics is the Hirka-i Serif, Prophet Muhammad’s (s.a.w.) mantle, which was brought to İstanbul during the reign of Selim I. Another sacred relic is the Sakal-ı Serif, hair from the beard of Prophet Muhammad (s.a.w.).
