Abu Ayyub al-Ansari
After the Conquest of Constantinople by the Ottoman Turks, a tomb was constructed above Abu Ayyub's grave and a mosque built in his honor by Sultan Mehmed the Conqueror. From that point on, the area now known as the locality of Eyüp has become sacred and many Ottoman officials requested burial in proximity of Abu Ayyub. His tomb was discovered by the Ottoman saint Akşemseddin. The tomb was rebuilt by Sultan Mahmud II in 1882, This mosque was the traditional site for the coronation ceremony of the Ottoman Sultans, where each new Sultan was girded with the Sword of Osman, the founder of the Ottoman Empire, obeying the order of Sheikh Edebali, Osman I also went to the tomb of Abu Ayyub al-Ansari.
