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).
Palace
After the conquest of Istanbul by Mehmed the Conqueror at 1453, construction of the Topkapı Palace was started in the year 1460 and completed in 1478. The palace was built upon a 700,000 square meter area on an Eastern Roman Acropolis located on the Istanbul Peninsula between the Sea of Marmara, Bosphorus and the Golden Horn. Topkapı Palace was the administrative, educational, and art center of the Empire for nearly four hundred years from Mehmed the Conqueror until Sultan Abdulmecid who was the thirty-first Sultan. Although Topkapi Palace was abandoned by the Ottoman Dynasty by moving to the Dolmabahçe Palace in the middle of the 19th century, Topkapı Palace retained its importance.
