The description you provided refers to the tomb of Suleiman the Magnificent, a prominent ruler of the Ottoman Empire. Suleiman not only oversaw the empire at its peak in terms of territorial expansion but also established significant legal and governmental reforms. However, you might be mixing him with Sultan Mehmed II, also known as Mehmed the Conqueror, who was crucial in establishing the Ottoman Empire and promoting Islam within it after the conquest of Constantinople in 1453.
