Mr @Imran Khan knows nothing about the history of Hagia Sophia, it's just his secularistic ego was HURT, so he went running on every thread discussing this issue.It is also not the first time that Ayasofya was closed to worship. It happened before many times in history. Catholic Crusaders looted, it saw civil wars and dynasty struggles, set on fire, damaged by neglect, damaged in earthquakes and so on... Many times during the Christian period, it was closed to worship for many years.
I would recommend him to read what the crusaders did with orthodox and Hagia Sophia.
