Prophesized by Prophet Mohammed as the overarching jihad goal of the Muslim world to conquer against 'the rule of the infidels', the world heritage site Hagia Sophia (built 537) was historically conquered by Ottoman Sultan Mehmet II in 1453 and converted into a mosque, marking the end of the Eastern Roman Empire. The building remains a litmus test of jihad, especially following its recent reconversion into a mosque in 2020 after nearly a century of serving as a museum. Eid prayers held in Hagia Sophia are thus of utmost importance since they mark more than just a religious ritual but also signal global Muslim might.
